I think you should pass on this one...what was his contact info again?
Seriously though, it sounds like a pretty good deal to me, even tandem tomcats are tough to find at that price, a lynx is much nicer.You can get another cheetah chair for $60 from aire if you want it. Sounds like the bare spots woukd be easy to patch or ignore? With the bladder system, a few thin spots don't matter as much as they would on other boats.
