Find a pro shop and get measured. Lots of bow shops sell used epuipment that they take in on trade. If they don't sell used equipment.. maybe they know of one of their customers looking to trade up.. that might have a bow that will work for you. Make sure that you get a bow that FITS you. IE draw length and appropiate weight. Just be sure that the bow fits above all.

At the very least get measured.. then look on the internet for a bow. Check out the classifieds here and over on Archerytalk.com.
