Welcome,
I have a 14 y/o neighbor that I hunt with. We religously hit the weekend yard/garage sales. You live in Texas (a hunter's paradise) and I would imagine there are some good bows in garages just looking for a new owner. Look to see that they have no cracks, twists and proper weight for you. And work the seller, if he is a hunter, knows your excitement, and your budget, he's sure to come to meet your budget. We've found a pretty nice Ben Pearson for $20 and Bear for $80 for him. Keep an eye open on TG classified too.
WELCOME to TG.
Quinn
