First question. How do you tell if a speaker is a good or reasonable price? Second I just purchased a CS400i center slighltly used, like new for $217.50 on Ebay. Good deal or not? Third. What is wrong with Sony receviers? I have a STR-DE975 running 2 RT10's, and 2 MIII rears, and soon the CS400i. I returned the Onkyo I bought in favor of the Sony. The Onkyo would kick off half way through a DVD. The Sony will run all day. With excellent sound and zero distortion.
