We don't charge for string installation or peeps at our store, if you buy them from us (Gander Mt, Harrisburg, Pa.). To that end I'd say you're looking at $25 or a little less for string and peep. Or depending on what string it could be as little as $15. If you'd like a single cam Zebra then you're looking at $35 or so, not that I'd spend the money for one. I do spend that kind of money, but get mine from Prostrings.
