Portable cd player? - best sounding portable cd player

I've used my iPod so far, I think, buying a CD, but there are certain things that I'm not sure. CD players have better sound quality, not more expensive than the cheapest? because I always thought that there are on the CD "analog", which should sound the same. but if they vary in quality, how much should it cost at least?
