A fellow on gj paid $200 for one at auction, but it had good readable text, and he got some other odds and ends in there with it....so say, 150-200 range? (winging it, *)
From a certain point of view I suppose a poor one is worth the $60, but I think for something like that I'd rather save up and get the nice one....
