One thing to ask the seller is whether the gas assist works. If it doesn't, it's probably a very easy fix, and you could likely get them to knock a few dollars off the asking price for the trouble. Other than that, it's a third-generation Performer with all attached components apparently present. I'd say $100 is a pretty fair price, but like all transactions, it comes down to whether the buyer wants it and the seller is willing to part with it for the agreed price. Worst case is that this Performer doesn't scratch your friend's itch, and he ends up with a severe case of Weberitis.
