I sell these for a living. Tomtom sucks. They have done one thing well which is to market their product. If they had put half the energy into producing an easy to use GPS that they have in marketing they would have something.
The others who say Garmin are correct. The Nuvi 200w can be found at Radioshack for $199.99. The Nuvi 205w is $249.99. The difference is the 205 shows posted speed limits and has a qwerty keyboard (200 has an abc keyboard). These two units are hands-down the most bang for buck easiest to use units out there. They both come out of the box eligible for one free map update from garmin.com. This unit does not have bluetooth and does not accept voice commands.
Definately spend the extra $50 for the wide screen. Remember, the screen is not only where you look at the maps but also where you interface with the device. It is a touch screen. The keyboard keys on the smaller units are almost small enough to require a stylus.
