Kind of DL dependent IMO. If your a 29" DL or better the Apex will suit you good. If less, the A7 might do you better.
I'd think about $400 would be my ceiling for what you've listed. It's a good bow, good arrows, good sight, but all "used". If it's exactly what your looking for, great, but if there is some part of the list your not after, you have to hold a line.
