Pricing a PDP-8/L

A friend of mine locally has happened across a PDP-8L in unknown shape. He wants to sell it on eOverpay. I wish to prevent this. To do so, I need to present to him a reasonable price that he can sell it at. The last -8/L I got was a rescue. The one before that was $200 in a 6' rack with high-speed paper tape and 12Kw of core (plays papertape Star Trek beautifully ;-) I have no idea what to tell him. He is a geek, but has no interest in preserving history. He just wants the money. Can anyone here cough up a reasonable estimate of what a PDP-8/L is worth? I realize that it's a tough question, but if I don't have an answer, some core-collecting weenie is probably going to have a trophy to nail to the wall. If it's worth more than I'm willing to pay, I'll gladly help anyone on this list with aquiring it. The machine is located in north-central Ohio, but the owner drives to work in Columbus every day. -ethan _________________________________________________________ Do You Yahoo!?
