Just make sure that the draw length is exactly correct, if not changing cams would make the deal not so great. The bow must fit correctly or you will never be happy. In most cases you get what you pay for. I tend to save a bit longer and purchase an upscale model. I think new from a pro shop tends to make the best deal for the long haul. You may pay up front but longevity brings the origional cost down year after year.
