A couple of years ago I picked up a Shakespeare Sierra recurve for $40 on e-bay. It's just like the one I used as a teenager back in the 70's. Shakespeare made a decent line of bows that were reasonably priced. My bow is 52" long and that's about as short as I'd want to go, or the string will start pinching your fingers. Just search e-bay for shakespeare archery, they made bows in many different lengths. Look at listings with lots of pictures and look for cracks and twisted limbs. There's no reason to spend more than $50 on one that'll get you started. I like a 45# draw weight for hunting.
3rivers archery is a good place to pick up accessories.
