As long as everything is in good shape, yeah, you paid a fair price for that. I do however, have a few concerns.

Did you shoot the bow first?
Is it set up to fit you, and comfortable?

You could have bought a brand new bow and set up for just a little more, but you weren't given the shaft to answer your question.

You are going to find that there is NOTHING in the world like bow hunting, and I wish you all the luck in the world. Just don't get flustered, it takes a boat load of practice and patience.

Welcome to the forums, glad to have you!
