I don't think there's very much risk involved when:
A. The customer spends the money to ship the pedal to you.
B. The pedal remains in your possession until the balance for the work is paid.
It's not like I'm asking him to build me a custom pedal without any deposit, and at the risk of non payment on completion of the project. In the end, if I default on paying what I owe for the repair, he can sell the pedal as refurbished. I'm pretty sure he'd have no problem getting the $160 I paid, easily covering the cost of what he put into repairing the pedal. Apparently this does not occur to Jack, and I am a KNOWN NO KNOW NOBODY delinquent Charlie... Or something to that effect. Wahoo!
