Go to your local shop and shoot some they have. Get a feel for what you like. Shoot a single cam, slaved dual cam, or any other cam system they have. Each will have a different feel. which one is best for you, only you can decide.
Shoot all the bows they have or will allow you to shoot that is in the price range you want.
Chances are the shop will have a few package deals with sights and all.
It's really difficult to find a bad bow nowadays. All the manufactures make very good bows.
Good luck and welcome to the healthy addiction of archery!
