Agree with the other posters. But don't take it to your average bike shop - try to find one that specializes in older bikes and will have the knowledge to properly fix up the bike. If you can spend $200 and completely fix up your Gary Fisher, you will have a significantly better bike than something for $200 from a department store. Additionally, there is a market for the frame and some of the parts (for people who collect and build vintage MTBs.) At the very least, sell it to someone who can give it the care it deserves.
