Well, I've got a guy I work with who is wanting to sell me his used Saturn and 3DO systems (just about the only major systems I don't have). I might be interested if the prices are right. What would be considered fair prices to pay for used complete systems? I've checked Ebay, and it looks like Saturns are maybe going for around $40 or so. Haven't checked into the 3DOs yet. Thanks for the help.
