Some of the Parker dealers around here will just give you the module if you bought the bow from them. No charge at all. Often they even have them on hand from swapping out with someone else. I have yet to find a Parker that wasn't worth the dollars it cost. Have shot the Phoenixs 32.34,36, Hunter Mag and Hunter Mag extreme, Buck hunter and ultra lite. they are all nice bows and in general will give you a good bang for your buck.
