Earlier I was looking for advice for some audio gear on a limited budget - I ended up buying a Pioneer VSX-830-K A/V receiver (on sale) with a pair of Klipsch 5 1/2" bookshelf speakers (not on sale).  I plan on adding some floor speakers and a subwoofer soon.   I was pretty amazed at the features available for the money compared to the last time I bought audio gear 20 years ago that I lost in the divorce.

I was slow in replying to your original question so I'm not sure you even saw my suggestion.  My response wasn't very close to your original question in the thread. 
  
A lot of people think you need a matched speaker set in a 5.1/7.1 surround setup, but I don't necessarily buy into that.  Most receivers have the ability to do room calibration with automatically sets the volume on the speakers.  I personally have a major hodge podge of speakers in my 7.1 system (Klipsch Chorus II fronts, Vandersteen 1b sides, Polk Audio RTiA3  rears, Vandersteen sub and center channel).  From my perspective it all blends together after room calibration and their volumes are set. 
 
My original suggestion still stands with a speaker and sub.  For floor standing speakers I would go with the ELAC Debut F5 or F6, and an HSU research STF-2 subwoofer.  I think the options in your price range will be limited if you want to keep it all Klipsch.
