The Klipsch were also too bright for me as well. My bedroom 5.1 consists of 4 Infinity Primus362 and a PC350 and I enjoy them a lot. They aren't bright....sound neutral to me. Definately, a bang for the buck when they go on sale at frys. Check amazon for current prices.
PSB and Monitor Audio are good prices at SaturdayAudio but little above your price range. PSB good prices at AudioAdvisor as well. If you are willing to stretch your budget, PSB and Monitor Audio are good buys.
In the end, it's always best if you can audition these brands to see if it fits your tastes. IMO, these brands won't be harsh like Klipsch.
