If you want to spend the time and money doing it ,give it a go!there is nothing like riding a board that you have made with youre own hands

,having said that simon is right ,you can buy production boards for under $600 if you shop around (and dont go to retailers!!

).i have sucessfully built about a dozen boards using composites(divinycell/corecell,carbon,kevlar,glass,epoxy whatever!!)and a vacuum bagging setup .you can build a board for under $500 using these materials but the cost comes into it when you paint the board,one of the best and strongest finishes is 2pack marine paint which is expensive and toxic when sprayed,and comes in **** all colours!and then comes the pads/straps/fins.if you want to build a board because you want to ride something youve made yourself then i recommend it but if you are just trying to save a few bucks then go the production board.
