CNB,

You can go to a local archery shop and look at some models. Have them measure you for your draw length. Most are adjustable, but you'll still need to know what you mean. From there you can watch the newspaper, craigslist, classifieds here ect. until you find a good used one. With christmas coming there should be plenty for sale both before and after christmas. If it was me, unless it's an urgent need, I'd wait till I found a GOOD deal on a GOOD bow. If you're not looking at it till next season, you have a good amount of time to wait for a good deal. Good luck.
