I agree with bumpin_blazer, first determine your price range then find a h/u that is aesthetically pleasing to you and has the options you want/need. All the high end brands make excellent units, Pioneer Premier, Kenwood, Alpine, Eclipse, etc. All I can vouch for is the durability of the Pioneer as I had someone break into a car I used to have and attempt to steal my h/u. But when they found out it didn't have a detachable face, they proceeded to rip the face off anyway. The same night we had a rainstorm and I found my Pioneer laying in a puddle in my floorboard. I plugged her back in, reattached my faceplate, and she worked perfectly for the next two years; then I sold the car. Best of luck in your search!
