Ebay try to find a bow on there..And trust me you can find a great bow relatively cheap. And of course its used..Or you can hit up somewhere like cabelas or gander mountain and get a nice name cheap compound.
something like hoyt, parker, fred bear, martin. All these bows manufacturers make a discount bow or a lower model. like bowtech has diamond, and hoyt has reflex. Do some research..I can say that they make a good bow and they are reliable...So look around...And youll find something. make sure your speeds range from 270-310 FPS and try to find a bow that has a package attached like a sight arrow rest quiver and stabilizer. Those are my tidbits and pointers. in fact right now im looking at gander mountain a parker side kick XP outfitter for $319.00 thats about the cheapest for a new decent bow.
