We have the Garmin Nuvi 660. Love it, love it! Purchased it from Amazon back in Nov. 07 for $400. Super easy to use, excellent prompts, the maps are easy to see and interface with while on the road. Fantastic in cities. Wonderful for long trips on the interstates. Constantly calculates your progress and shows your arrival time. Lets you know how long a traffic delay will be so you can decide if you want to detour. Recalculates if you make a mistake, or you choose to head off course for something. Where's the nearest Starbucks? So much more useful that just getting directions from Point A to Point B. Impressed with the accuracy of the maps - so far "Ms Garmin" hasn't led us astray once, has even taught us some excellent shortcuts we never knew existed! My husband likes the hands free cellphone feature on the 660 so it goes to work with him everyday. You'll love having a GPS.
