Great suggestions from the other members.
I would only add this..
Spend as much as you can afford and buy the best you can afford.
Bow hunting gear can be like buying fishing equipment. You can get by with cheaper stuff, but you will probably enjoy the sport a lot more in the long run but buying better equipment right from the start.
I bought cheap fishing equipment when I went back to that sport. I would up buying the better stuff later. It simply costs more to buy it twice.
Like others have said, I'd rather have a quality used bow in good shape, than a lower quality bow brand new.
