I just purchased materials from Binghams for my first glass bow attempt. I got a limb package for a 60# R/D. The materials are not here yet but they were more than helpful getting what I need. I will update when I receive the packages but my first impressions are good.
Bingham is a reputable business that has served the archery industry well. I'm sure you will do well with their kit.
Be sure to let us know how it goes.
