B&C, for 450 bucks you can get just about any 2003 slightly used bow you want.

As to the drawlength needed....your best bet would be to go to a reputable proshop and have them measure you. If your wingspan is really 72" , that would put you at a 28.5" drawlength, give or take a 1/4" .

If you have trouble finding a good bow in your price range, drop me an e-mail. I would be glad to help you track one down.
