Looking for a cheap (read free) boost radio for my car. I got stuck with the wave one and can't fit anything to it at all. It's a real pain.

Seen them on eBay but they always seem to go for crazy amounts so thought I'd ask around see if anyone has a resonably priced one or even seen one on eBay that maybe other people haven't really noticed.

Don't care if it's even just a tape cassette player. Just want to fit an AUX port without having the hassle of buying a bunch of cables to change one set of inputs to the other.
