I'd agree with checking out the Mission line for under $300. However, you're best bet is to go listen to stuff costing more like $500, deciding what you like, then looking for it on Audiogon. Hifi store people (like me) don't like this, but I recommend it anyway if you're on a budget. Just find a store you don't like, since you don't want to alienate the guys at a store you actually like.
Also, I can't believe I had no idea this place was here until yesterday. Head-Fi without all the crap = .
