H20 do you already have surf tabs or AA plate, do you need the bags included in the Gen 2 package? These are some of the variables that will determine the price. I was around $3500 but I did not require the bags and did not have surf tabs already so no glass work to fill previous holes etc..
As far as is it worth it? I say absolutely, I was not sold on it originally and now believe it is one hell of a shaping device on my X30. They say the X10 surfs excellent out of the box with Gen 2 so you may not need to play as much as I did.
