I' m looking at buying an used pse XSR-3000. It' s daul cam, 36 inch ata, 65% let off. comes with a quiver, string whiskers, limb savers, and a stablizer, along with a new zebra string. He' s asking $100, good deal? Is the bow a good bow for a beginner? I mean I know it will provide enough power to take a deer but is there a big down side?
