What is considered a good deal? I really like the Rino 120 that has the 2 way FM radio. It is a sweet GPS that is really easy to operate and has some very cool functions. I think it goes for about $250. I used it all over Iraq with excellent success. It had better accuracy than our millitary pluggers. You are also able to geolocated other people that have the same system w/in a certain distance. The newest ones out were just upgraded with more memory for maps.
just my cents
