I think you're making assumptions that may or may not be correct. You assume he bought it from a "kit cutter". My reading of the post sounds more like he bought the kit from another hobbiest, not a professional. The OP searched out another hobbiest and asked him to make the parts so he could make a wing. Sure, $80 is a lot for a set of ribs from a kit cutter that just plops a couple pieces of balsa on the cnc laser and hits a button, but I don't see laser marks on those ribs, so for a hobbiest to break out templates, trace all the pieces out, cut them out, sand them, pack them and make a trip to the post office sounds more like he did the OP a favor for only $80. See how different things can be when you look at it from another angle?
