I second the Garmin Nuvi 660- got one about a week ago and have been loving it so far. While its a bit out of your pricerange, the 360 has most of the same features with a smaller screen, and there is a slightly cheaper version that lacks bluetooth and maybe the FM receiver.

It's easy to use, works fantastically in the car, and easy to transfer to other cars. I used it in Phoenix to get me across town to an event, and it worked flawlessly, also took it to San Diego to get from the airport to a hotel a good 30 min away. Check out epinions reviews...
