I think you are in the ball park 42 with your choices so far... specially at that price point. take your time and wait for a deal to come to you.
one thing that surprised me was there are additional costs associated with TT playback. you can get a high output cartridge, but really a low output is better, which means set up or preamp that can amplify the signal. budget a few hundred for the HO/LO cart and if you go with a step up... a few hundred more.
TT's prices have really firmed up over the last few months, so you may need to step up a bit in pricing. Once you get into the 500-750 range, doors begin to open up in as far as options.
in addition to eBay... keep an eye open on Craigslist and at the 200-400 price point, consider your first TT purchase, not to be your last. you will want to upgrade later.
