Ask yourself, "what can I afford to pay for the bow, and of course, back it with a guarantee. Can another student afford one of my bows?" Many of us have been in the broke student mode at various times so we know that part of the situation. The difference in economies is important to consider.

Guarantee, yep, those are the words I distain. Can the customer assure you with any accuracy they won't, didn't, and never allow their "friends" to draw the bow built for them to be drawn only by them? You assume liability for people, even people that were never intended to draw the bow you made specifically for that customer. I have lived this! 27 inch draw bow given to a guy that overdrew the bow considerably by a friend. Lucky not to get sued, never again! That's the reason large companies moved on to glass.
If you are using ALL natural materials, the best bowyer can have failures. There is no way you can guarantee natural products, I know people do, but they take major liability concerns that go along with it. The ability of the bowyer without doubt should be judged by the consumer. The consumer should also educate themselves on the basics of all natural bows well before picking their bowyer of choice. Obviously the bowyer should have talent, but the consumer should bring knowledge to the table and pick flaws before a purchase. My opinion.
