Don't go to ebay, dont borrow equipment, don't buy from a yardsale.

If you're serious about getting into archery and archery hunting, go to your local pro shop and have them fit you with a bow. You're going to frustrate yourself to no end trying to learn this sport with equipment that isn't fitted to you.

If you can't afford brand new equipment, you can purchase used stuff from your pro shop. Just go have yourself fitted so you know exactly what you need.
