New or refurb doesn't matter as much as the brand and warranty you are getting on it. That's really the key, because if you are paying for shipping and don't intend to use it right away, then you may find yourself outside the return window and may not even have a warranty on a piece of refurb gear when you go to use it. I had this happen with a Denon piece I got and it was almost a total loss for me. But, had I gotten an extended warranty, then I likely could have taken care of the issue through warranty work. New products tend to have a longer warranty, and many stores will really work with you to take care of issues. Also, you want to keep a close eye on changes that occur from model to model. You may find that the older product doesn't support a feature you want, or that there is a newer cheaper product which meets your needs (2113 instead of 2312 for example). When it comes to bleeding edge products like receivers, I tend to buy new. When it comes to solid state products like amplifiers, I often buy used. Speakers I've gotten both ways and I've had tremendous luck buying used gear over the years. But, as always, anything you purchase needs to be setup and tested almost immediately upon receipt to protect yourself.
