Welcome to the best xbow forum on the net! I just bought a "Crankaroo" for gal pal to cock an Excal for $84 from Danny Miller at [740] 483-2312. They only work on Excals. The 10 pt Accudraw is quieter, permanently mounted to bow, generally considered the best out there, but is around $200 and you have to have it installed by someone who knows what they are doing on any bow it will fit on besides a 10 pt. I'm an Excal fan, you can get a Vixen or Phoenix fairly cheap off of Ebay at www.bowhunterssuperstore.com Good luck!!
