im just throwing out my guess. i figure for both limbs it would be around $300-350. For the cam, maybe $100? $50 for a good string. $6 for the peep. all this plus the labor....$500-$600? would yall think that is a reasonable guess?
You could always tell your buddy that's how much it costs..........
(off the top of my head the $$ won't be anywhere near that, probably not even 1/2 what you think......but I don't have a parts list handy to give you an idea of actual cost)
