I have a Tom Tom Go 720, Brand New, unopened for $170 (list for $399). Also have a Tom Tom One v3 for $75 including a Ram Cradle for a MC mount. This one is off my bike, perfect working condition.
I've had a 720 since they came out. I really like mine. I travel a lot and carry it with me for use in rental cars. I like them more than Garmin, the Garmin screen is like a cartoon in my opinion and they don't give you near the amount of info on the screen
