I wasn't going to make a recommendation but since Ethanh brought it up. The Unison Unico, or one of their similar models might work for you. I am using a Unico right now and hope to keep it for a while. It's only 80 watts but it drives my Meadowlark Kestrels very well.
Simple, clean and nice sound and at used prices, well within your budget. Also not as old as the Classe.
