Need a Bose CD deck for 2001 Pathy

[captluv]

Anybody know where I can get an add-on cd player for an 01 pathy. It's got a Bose tape deck but no CD, so it's a single space with the pocket piece above it. Is there a single space cd player I can add, or do I have to buy a whole new tape/cd deck? They're pretty pricey on Ebay, anybody know where I can get one cheap in the next few days (I'm in Los Angeles)? Thanks.
