As title says, looking for a cheap CD Player/Head Unit to replace the factory stereo in my car.

Requirements:

1. Very good condition, don't want anything busted/scratched up.

2. Must have an AUX port in the front so I can hookup my iPod.

3. Must have all hookup/cables etc for it.

4. As cheap as possible, I'd like to find something around $50 if possible.

Thanks.
