Best new or used speakers for under 3K?

I am redoing my sound system and am looking for new main speakers. The center, surrounds, and a good sub will come later. For now I want to focus on high quality mains. I have already received the Integra DHC 9.9 pre/pro and the B&K 200.7 amp is on the way. I want to run a 5.1 system bi-amping the mains. I have been looking hard at the PSB Synchrony One's and the cheapest I have found them is about $3,600 +S/H. I need some suggestions from you guys. My room is about 12' X 14'.
