Which good CD transports can be found in the used market?

I've used the Mac "Superdrive" cd/dvd transport that came with my Mac Mini to play and rip CD's into iTunes. So i know that I'm not getting the best quality 1's and 0's I listen to.   As I'm retired and on a budget, am unable to go out and buy a Cambridge CXC or the like.   Which older-model cd players, dvd players or stand-alone transports do you suggest I consider ...and at what price might I be able to find them?  Thanks, people!!
