Various speakers from that series have been on close out pricing at Frys and Newegg, in case you need to complete an HT setup. The RC-62 center I got at a ridiculous $134 shipped, but it looks like the going rate on sale for those now is $199. I got the RB-61 for rear surround for $199 shipped from Frys. What I do is put a tickler on slickdeals.net and I get an email when someone posts that they are on sale or will be soon (Frys lets the word out before the sales).
These are deceptively inexpensive given their sound quality. With a proper amp, you have a high end performing system, no doubt about it. My main rig is Thiel CS3.5s with Odyssey monoblocks and even with a middling home theater amp I'm having a hard time deciding if that system is in fact better than the Klipsch. The clarity is very alluring and voices seem so much more realistic. No harshness or fatigue at all. I will say that they are also "revealing" like many high end speakers seem to be and I have rotated two amps through them and you can really hear the difference between equipment.
