Refurbished/Pre-Owned == Positive
I'm currently running a refurbished Yamaha RX-V2500 (uBid) with a pre-owned Sunfire Cinema Grande 200x5 amp (AudiogoN), refurbished VR3s (OneCall), pre-owned VR12 (HTS forum) and pre-owned Axiom QS8s (eBay) in my main setup. This is coupled with a pre-owned Hitachi 61SWX12B 61" HD RPTV.
Also I'm running a refurbished Denon AVR-886 (uBid) with a pair of pre-owned CR65s and VR10 ( both eBay) in a second setup along with a refurbed Yamaha RX-V659 (uBid), Boston CR55s and Boston Bravo (also both eBay) in my bedroom setup.
Suffice to say I wouldn't be able to afford half of this equipment if I didn't buy refurbished or used. I may have caviar taste, but I'm stuck w/the peanut butter wallet...
In my several refurbished and used purchases, I can honestly say I have been very fortunate and have rarely run into someone selling a "lemon". This is obviously one of those "risk-reward" situations, but in my experience, I've found the reward far outweighs the risk, at least when it's come to my home theater purchases.
Good luck!
