In my humble and amateur opinion, building a handle is not akin to building the bow. its all about the tiller, never mind the handle. if you buy factory limbs i suspect you may not get the immense satisfaction many of us get shooting a bow we made. i haven't made a glass bow (i used to want to) but my take on it is its easier, but requires more expensive tools. building a couple wooden bows can teach you a whole lot about bows you never thought you ought to know, and will certainly carry over to building a glass bow. to each his own, but im in love with self bows. i just built an all wood laminate bow, and it doesn't excite me as much as a self bow. don't know why... it just doesn't. so my answer to your question is get yourself an osage stave.
