To the first question, I placed my Nicro vent over the head Like Peter did. In that location it draws air through the saloon from the leaky companionway crib boards and the sliding hatch, and through the head area. It is a little bit of a nuisance when I'm working at the mast, but I have been able to avoid stepping on it or tripping over it (most of the time, anyway). There aren't many other good locations on the cabintop. I thought about putting it on the foredeck, to draw through the v-berth as well as the rest of the interior, but the foredeck gets a lot more water splashing over it and I don't think the unit would provide enough protection against water coming through a hole up there. The Nicro unit can be closed from the interior, but it would be a nuisance to close every time I sail in bouncy water and then have to remember to reopen it afterward. I haven't noticed any leakage at the location over the head.
As to the second question, the Nicro units are very popular but overpriced, mainly from lack of competition. They are also very unpopular with many people who have them (read the wealth of opinions on various online message boards). The manufacturer sells a rebuild kit, including a replacement motor as well as unnecessary parts like the two fans (one draws air in and the other expels air) and the plastic insect screen. They also sell (separately) replacement batteries. However, if you do some online searching you will find descriptions of how some people have come up with less expensive alternates for repairing or replacing their Nicro units. If you keep a battery charger connected when you're in your berth, or if you have a large enough permanent solar charging system, the non-solar Nicro unit might be a better choice.
The trouble with a destination - any destination, really - is that it interrupts The Journey.

I like the Nicro vent but the motor in it usually goes after about 2 years. I do run mine constantly, all year round, since my boat remains in the finger slip. They sell a replacement motor kit but it is semi-expensive and a new Nicro is a lot to shell out every 2 years or so. What works for me is to catch the Nicro Solar vent when it goes on sale at West Marine and then buy the 3 year warranty which West Marine offers for electrical, etc marine equipment. The cost of the 3 year warranty believe was around $13 or so if you catch the Nicro on sale. (The warranty is based on the purchase price of whatever you are buying.) Having the 3 year warranty, there is probably a 75% chance that the vent will fail during the 3 year period, especially if you run the vent all year round. Then they give you a new Nicro as a replacement for free. However, if you do not run the Nicro all year-round, then it is likely the vent may last longer than 3 years and you would then lose out on getting the free replacement.
I had a vent hole in cabin, near the cabin/head bulkhead but it had a cover on it. I suspect the PO at one time had a Nicro Vent but then replaced it with a cover. I purchased a Nicro Vent and installed it in the existing deck hole and it fit perferctly.
A popular place for a solar vent is in the forward hatch, which (1) keeps it out from under-foot, and (2) avoids cutting a large hole in the boat. If you decide on some other type of ventilation, you can probably replace the hatch more easily than close the hole in the inside and outside of the cored deck or cabin-top. A downside is it does make a little noise that could be annoying in the V-berth. But from there, you'll hear one in the head, too.

Thanks so much for the help. I'll probably end up putting it over the head but like the forward hatch idea as well. And I'll likely get that protection plan for it also. Much obliged to all.
Stay safe,

The singular point of the solar-charged battery vent is to continue forced ventillation overnight as outside air cools and drops its moisture, while inside air starts to do the same but, left inside, drops it in the form of condensation in the cabin. Passive vents tend to fade out at night unless you have a consistent overnight breeze. One option is to wire something to your electrical system—another is to use a Nicro (solar+battery). Both have disadvantages—battery depletion vs dubious reliability. Pick your poison.

One minor downside of mounting a solar vent or passive vent on the forward hatch is that the old jib sheet will occasionally hang up on it when tacking.

?? - Just to explain my experience with that solar vent and the jib sheet ... If I am tacking to windward and I come about I’ll release the old jib sheet (now windward) before hardening the new sheet.
Sometimes as the jib comes across, the sheet will hang up on the forward section of the vent and that will prevent me hauling the new sheet all the way in.
If I knew then what I know now - I probably would have not purchased the vent or found a different location for it.
Perhaps next time someone is parting out a C25 I’ll request their unmodified forward hatch as a replacement.
I was unhappy with my Nicro vent because it died after two years, soon after the warranty expired. Then wo years passed and it started working again. Go figure...
Likely a small point of concern, consider if you will install a forward head door between the v-berth and the head. I am working on that now. My vent is unfortunately placed precisely where the door will close. In retrospect, I would have preferred the vent to have been placed a few inches aft so that it would be fully inside the head with the door closed. On the positive side, it's farther forward and so does not interfere with mast work.
