Check out your local pro shop and ask around. Listen to what the local "pro" tells you and don't be afraid to ask questions. Then leave and check out another pro shop.. do the same. After you have tried out a few bows, and really asked some good questions in a "hands on" envirornment. Choose the bow you like.

Choosing a bow is a personal decision. Make sure you're confident in it.

Better manufacturers include Hoyt, Bowtech, Mathews.. etc. But all these manufacturers have cheaper lines that are still good bows, especially for beginners.
