Hi, I'm currently debating on which set-up or package to get. I found the ONKYO HTS760 for clearance, which it has gotten really good reviews. The other choice is the JBL CINEMA PROPACK 600-Z. They both are refurbished, and within or about the same price range. WIth the JBL, it seemed like they have a history of failing, should I be concerned with this? Any had experiences with refurb onkyo or JBL equipment?
