No opinion on the price, but every display model I've bought from BB has carried the full warranty -- so it's just like buying a new receiver. That is, assuming you can get all the accessories. However, I've always been able to convince the sales people to give me all the accessories I need, even if they come from the current display models. I.e., "I was in here yesterday and the guy told me that he would give me a working remote and microphone ..."
I don't think I'd buy either model without the big remote and setup mic (unless you already have them, of course ...)
