In this price range, you should seriously consider the ART SLA-1. You can get a new one for about $200 delivered. There was considerable buzz about this amp a few weeks ago on AudioGon, and a few of us took a small gamble and ordered one to try in our systems. In the end, I decided to stay with my Plinius SA-102, but the SLA-1 performed admirably in my system with components costing many times more. Check the archives for more detailed information. There is a splendid review by one of the members that nails the pros and cons of the SLA-1. If I were just starting out and working with your budget, I wouldn't think twice about it.
Good luck.
