So I have the opportunity to pick up a 8100 for under $1K that was used for less than an hour. The guy recieved it as a gift and said he has no use for it. My dilemma..... the guy does not have a reciept for it. Will I have any issues with warranty since I am not the original owner and would have no proof of purchase? I am nervous buying used but I may be getting this thing for $600-$800. I'm waiting for him to give the the S# so I can call epson but I figure someone here can give me advice. Should I jump on this deal??? Are there any other concerns I should have?
