I know a couple collectors that would offer $200 for it, with a straight face :?
He's asking a bit much, without the original bullmoose and other original parts, though it's hard to tell with the pics he has posted. He needs to do a real parts list (might have quite a few original parts, it has the 600 headset) and better pics, and he might get a couple offers in the ballpark of what he's asking pending condition.
With all original parts and in good condition, his price is reasonable to good.
