Car GPS Systems

[KTorak]

I just got a '96 Jeep Grand Cherokee...and I get my license in March. However, one thing I have been looking into is GPS units for cars. I travel alot out of state to places that are unfamiliar to me and i'm looking for an *affordable* GPS system that I can mount in my Jeep. I've been just looking around and there are many good units..I just don't know which one to choose. Does anybody have any good suggestions for units they/someone they know used and loved? As well as units to avoid?

I've finally gotten sick of Mapquest maps and the such...and one big reason is if i get "misplaced" it is really hard to get yourself back on your route, where as a computerized system will show you exactly where to go. Also, reading a map while driving isn't the safest thing to do either...GPS units help combate that with turn-by-turn audio things, and you can just glance at it to see where you are/where you need to go.
