I built mine from scratch using the plans from ultimate. It is a lot of work!!!!! I cant tell you how many hours, but alot. Just buy it. I saved a few hundred bucks, but the cost gets up there especially if you buy the laminate for the sides. Also alot of work to put that on! Just save up! I probably spent 30 plus hours on mine. It came out great, but I could have used the time elsewhere.
