I have some used boards in both Prototypes and used older models for sale ranging from $700 to around $1300 without fins and straps.Some are IKA registered and some are not. If you are participating in an IKA event, they need to be a registered board.
I have about 4 different models with various cutouts and they are all very nice and lightweight. I can sell them for $1000 each. They are barely used also as I build them to test against the others in route to the current model for 2013 called the 69 S.
Let me know so you can get one before I sell them all.
