I would not be surprised if this Diamond Dave is reading these threads and will just buy the kit himself. Seems logical. That's why I would have already bought the kit if I were in your shoes. He who scores the kit scores the deal and/or a great flip.
I somehow don't think he could.. He'd have to learn to speak French and there's no way that the seller would go through all that trouble, even if Diamond Dave does offer him $500.. Whatever the case, the decision to buy will be determined by Dave's drum shop from Ottawa, Canada, if he even responds to my email. Hmmmm
