The older JVC's are excellent. I have a single disk, single cassette (manual), no remote, but, with detatchable speakers. It actually images a little. It has a nice, mellow, rich sound but, no slam. I bought it for $99 about 7 years ago. It doesn't look dated and hasn't given me a single problem.
This is the second JVC I have bought. The only reason I bought a new one was because the old one didn't have CD. The old one still works and it's about 15 years old.
Keep it as simple as possible and you will have less problems. Avoid units with remotes, motorized cd-drawers, etc. This will not only help the unit last longer but, save weight and space when transporting it... oh, and the batteries will last longer.
Good luck with your search....
I did find these that might be good:
