I would go to an archery store and have them measure your draw lengthy and talk to them many bows people sell or in bad shape cracked limbs they don't even know about. you may pay a little more at a archery shop but they will help you with your set up and pick a decent used bow. many have ranges for you to try to see what draw weight you are combfull with. if you by a used bow off someone take it to a shop so they can check it out before you shoot it to be safe.
