OK, I'll play devil's advocate here... sketchy sellers aside, WHY do you want a FX1? (here come the flames). Have you ridden one? Has your wife ridden one? Do you like how a kawi 550 rides? It is an athletic ride, not the stability and ease of riding that you get with a SJ. Is that what the wife wants?
I think the FX1 is a love-or-"it's OK" ski. There are a core group of riders that swear by them (once you change out the pump). But I'd say they are a hardcore minority. It has some nostalgic value as being a rare ski that Yam only made for 2 years? Basically a 550 handing with a power and reliability of a Yamaha 701. Was meant to be the slalom/freestyle king back in the SN racing days. Very light, very agile and I have mad respect for the FX mafia guys who shred them in the surf. It is a REAL Rider's ski, old-school- a throwback, no training wheels! LOL!
Is that what you're after?
(again - I'm sure the FX fanatics are gonna hate on me now) but I just wanted to make sure you are aware of what it is you're looking for.
FWIW, I don't love or hate the FX-1. No desire to own one though. I rode one of Tricky's once that did over 60mph - holy chit!!!! hang on! Dancing on marbles!!!
