Anyone know anything about GPS devices?

My wife just got one (Garmin/nuvi) for her birthday (Nov.7th) and it was the second from the top of the line available at that moment I beileve. It was a bit more than a $150 and worth it. Simple to use and updateable with maps as well as add on's that can be purchazsed seperatly. The next model up had them included. But some of the options seemed unwarranted or not needed for her. I'd buy another one for my daughter in a min. flat when she starts driving.

I'm not sure what else is out there and bang for the buck wise, but I would for surley recomend this to anyone. Pay the piper.
