Comparing New vs Refubished Printers?

GraWil asks: "Does anyone have advice on purchasing a color laser printer? I'm trying to decide between getting a new small 'personal' color laser or a used/refurbished workhorse. For the roughly the same money, I can either buy a Xerox 6100 or a refurbished Tektronix 740/750 or even a tabloid sized 790. I've had mixed luck with color HP and Lexmark printers but I'm open to any suggestions at this point. There are a fair number of reviews but none of them ever compare new with the old."
