A couple I notice include the MA RS1 for $425. The big brother RS6 was one of the most popular at its price point. If there were any complaints, some thought of it as a bit bright.
Another I notice is the Quad 22L. The red alarm here is that payment is requested via money order (where the RS1 above could be that, or paypal, or cash). I've heard this speaker. It is quite short for a "tower" which could mean that tweeter placement is too low respective to you, depending. The finish is very nice, particularly considering the price point. I found the sonic personality to be warm, pleasant, unoffensive, but perhaps veiled.
There is also Energy RS30, but I have nothing to offer here specifically, except that I know this brand is a good value. I cannot say if this deal if of particularly good value. $620.
There is also a pair of Paradigm Reference Studio 40 V2 in rosenut for $600.
OH CRAP. I just realized this is for 5.1. Ummm . . . .
Anyways, good luck.
