The Diamond line of bows would be an excellent choice IMO. One in particular called the Razors Edge will not break the bank and you get alot for your money with this setup. I believe it is retailing for around $350. Large range of adjustments for draw length and draw weight. I think this is one of the best "reasonably priced" bows on the market. Helped my girlfriend pick a bow and after shooting a Mission, a few Fred Bears this was the best choice. As stated above, the Hawk series from Hoyt is another great bow for the money. Good luck bud, shoot them all and pick what feels right to you.
