The only bows on that list that will be under $600 brand new is Reflex, and Diamond. I would really look at the diamond, or as was mentioned above already the Martin Bengal. That Bengal is a fantastic little bow. I have sold probably 10 of them over the last few months to people that didn't have the $$$ for a high end bow and for a hunting specific bow they really can't be beat. It is very likely that I may end up shooting a Martin next year and if so I wouldn't hesitate to shoot bengals for a hunting rig. They are just as quiet, smooth, and shock free as anything out there now including the big name brands. The $399 price tag is the best part of the bow.
