great bike, I have two of these. Bought one for $100 (a steal) and paid about $350 shipped on Ebay for the second one. I would value yours between $250 and $350. Maybe get the membership and try to sell it in the C&V Classifieds here first, these seem to be popular frames and they ride very well even in original configuration.
Another option is to part it out, Frame/Fork would prob bring $200+ on Ebay, looks like a Brooks Saddle which would prob bring $50-$70. Super Maxy crankset is fairly desirable, the wheel set is nice if you need it to complete a build, etc. Hate to see complete bikes parted out - but I have found this is the best way to get fair money for tall bikes as shipping complete tall bikes on sold on Ebay is typically over $100
