Well, those of us who buy refurbished things do take a chance.  But an equal number of times, I've bought brand new items and they show up DOA.  My purchase had some very odd undiagnosable issue.  Support worked very, very hard to try to make my unit work so as not to inconvenience me.  But... didn't win this time.  They promptly sent a return label for the sick computer and sent one of equal or better specs out same day. Really can't ask for any better than that. It's a machine.  Sometimes you win, sometimes not... so it boils down to the people backing it... and these guys were awesome.
