Price is very fair assuming it's mechanically as good as it looks.
It's true that a race ski isn't going to have that grunt you expect, but you are coming from a SXR, which is built to race and has high porting. You will be happy. if you decide you want to go for more snap and less peak horse power, change out the pipe, and sell the motor (assuming it's been race ported) to someone more interested, and get a freeride ported motor and a B-pipe.
$3800 is a great place to start. You may have a race boat, but you'd have a small fortune to sell/trade on freeride parts if that's what you want. It's not like you're buying a -5 flatwater ski you need longer to race.
