A Denon DL-301 MK II is a really nice cartridge. From a dealer they are $400. I saw one on an auction site for $300 -

It's a nice entree into the world of vinyl just to see if you like it or not, but if you care about sound quality, you'll end up selling it before long. Instead of going through that exercise, I'd suggest looking for a used table of better quality, at least equivalent to the Music Hall 5.X series.
