Mike,
Speakers have a very distinctive personality so you have to listen to them yourself and decide what sounds good to YOU.
You can find really good sounding speakers for around that price range. Just will have to find a REAL audio/video store though - not CC or BB.
A suggestion:
Take a listen to the B&W 600 series speakers. You get one heck of a sound for a reasonable price. You won't find these at CC or Best Buy though.

I am not biased because I own these - I gave my 602's to my brother last year.
Also, take a listen to the NHT line.

Personally, I use NHT 2.5i's for the rears and NHT 3.3's for the fronts (with matching center speaker) but those are out of your price range.
