So wifey already has a GPS now.... sounds like you still need one for hunting and driving, and maybe flying in the near future.
As the guy who restores a 1918 18" lathe instead of going out and buying a new Grizzly, I do things a little differently. My GPS is a Garmin Etrex Vista handheld. It is a ful moving map GPS with 24megs of storage (enough for about 1/4 of the continental US down to hog trails), and also has a real live barometric altimeter and a mag compass for use when not moving.
Discovering I was also driving around with my head in the console, I got the little suction cup windshield mount, but the suction cup died. I found I could wedge the GPS between the windshield and dash and forget the $25 mount. It has great reception in that position and provides a "Heads-Up-Display" so you can get the info you want and still see the old woman that just stopped on the entrance ramp in front of you.
With the detail map CD, it can give you the attractions, gas, food, lodging info etc... when you point at an exit. It runs on two AA batteries for about 16hrs even with the backlight on. I use a set of NiMH rechargables. Only get about 12hrs out of them, but I carry all four and the recharge overnight. They have a 12V adapter for the car or an airplane with a 12V system.
This GPS has no aviation database... at least the one you buy doesn't... I literally took a weekend and sat down with the A/FD for this area and loaded up all the NAVAIDS, airports and such using the lat/long coordinates to establish waypoints. I wouldn't try to fly an instrument approach with it (unless everything else in the airplane went out!), but it kicks BUTT for VFR flying.
I fly backwards to most folks. I fly by VFR pilotage and use the GPS for verification instead of staring at the GPS and looking out occasionally. Just what I got used to. This one has an HSI, but if you can fly it, you probably should be in airliners. Full-width deflection is 1/4 mile. I use the RMI display instead. I built a little aluminum yoke mount that attaches to a Cessna yoke with HF mini-bungees.
For hunting, it is waterproof, about the size of a cell phone, weighs nothing, and is very cheap ($350 or less). National forests and such are loaded, too.
Bad points. The screen is only about 2x2", so it can be hard to read, RMI or HSI is not a problem, but a cluttered zoomed-out map is nearly useless unless you have it up close. It doesn't talk to you, you have to figure where to go yourself when driving (I don't consider this a negative personally). The CD for the fine detail is about $100, but it is worth it I think.
I have learned one important lesson with the high detail maps. When I first got the GPS, I began going out and driving for fun in my 300ZX turbo, using the GPS to find alternate routes. Never once did it lead me astray, every road went exactly where it showed. The problem was that it did not tell you what KIND of road this was. Ever been 4-wheeling in a 300hp sports car? After doing so inadvertently a couple of times, I decided that was not such a great idea.
