Nobody on this site, or any other site, will be able to tell you which bow is right for you. I normally suggest you shoot as many different bows as possible and figure out which bow feels the best to you. However, that is hard to do when you are looking at purchasing a used bow. Know that longer axle-to-axle bow are more forgiving to shoot, as well as longer brace height bows are mroe forgiving to shoot. While they might be a bit slower, the ease of shooting is important for the beginner. Take a look at www.archerytalk.com, they have a large amount of bows for sale in their classified area and I am sure you will be able to find something there in your price range.

Good luck!
