What AR34 said. Go to a pro shop and get properly fitted to a bow. Then learn to shoot it properly, save yourself some grief right from the start. Most every shop will have a particular brand that they will suggest, but the thing to remember is that most all the known brands these days offer pretty good bows. My opinion, and everyone has one (especially bowhunters), is that Hoyt and Bowtech are hard to beat. For a starter bow, their offshoot brands are good value, Reflex and Diamond. Also, since you are rigging out new and will need everything, I would look at the package deals that include most of what you need right out of the box for a reasonable price.

Good luck and have fun!
