Hi guys,
I just picked up an 
Onkyo TX-SR501 from our local Circuit City that was going out of business.  They were selling all display models so I got it for about $180.  I thought it was a pretty good buy, was I right?
It replaced my Kenwood receiver that came with an all in one system, next I'm going to replace the center channel and the sub.
Since this is a 6.1 receiver, I was wondering, what kind of speaker should I get for the rear speaker?  Another center channel?
