Welcome to the obsession...
Good advice above. You might look for a bow that meets the minimum draw weight you can hunt with in your state. Like was said, used bows abound but BE CAREFUL! If you are not sure what to look for on a pawn shop or garage sale bow you could get a non-shooter. There are MANY good new bows for under two-hundred dollars (yes, almost all of them are imports... so what?). Either a take down or a one -piece bow. You will get A LOT more help from the good folks here on TradGang! My small input would be to find a bow with as similar a grip to your compound as you can find... as far as being able to shoot with a straight wrist. My thought is don't start your Traditional Archery adventure by having to dump EVERYTHING that is familiar. You will have enough fun trying to learn a good release and "sighting system" (GAP, string/face walking, Instinctive).
