There are kits and there are KITS. This isn't a U-Finish "kit". This is a man who knows his woods and bamboo from years of experience, picking out two really nice pieces of material for you.
You still have to get the Smooth-on, tip materials if you want, glue things up, decide on the design (flatbow or riser handle,etc) layout the design and cut to the dotted lines, then tiller the bow yourself.
Heck I've built a number of bows over the years, and if I wanted to make this kind, this is exactly what I'd buy.
