If it's not too far of a drive, I got my nephew set up last year with the bow Chevy is talking about. I won't plug a specific name, but they are in Boonville and were great to work with. As a general rule, I use your same philosophy of buying used. I'm not sure that is the smartest thing in this case. The bow we got came totally set up. That included adjusting after he would shoot at their range. You could probably negotiate a half dozen arrows or a release which would negate any savings in buying used.

The only other thing I would consider is a range finder if you don't already have one. Particularly if you are hunting a field edge from a blind and you don't have reference points. It will also allow her to practice at odd distances once her pins are set. Halo is a decent brand and you don't have to get too expensive ($100). Try as I might, I just can't seem to get deer to come in on 5 yd. increments. Good luck and congrats on getting to spend some time in the woods with your daughter.
