A bow is kinda like a women, you gotta find the one that works best for you! so my advice would be to shoot as many as you can in your price range. You will know once you shoot a few which one fits you best. Good luck and most of all have fun!
Another option is to look for a top of the line used bow ,built after 2006 .Bows seemed to hit a plateau after that in my opinion. That way you could have a top of the line setup for a bottom line price.
