I think the price of the GE Kabuto might be a little low. I sold the Kabuto + <2 keys in sweets pretty fast (less than 3 days) for a GE Chieftain's (sold about as quickly for 66 keys) + Stormy Storm Bonk Boy. If the 4 month old price on the Bonk Boy is accurate, that means I got more like 6.55 out of the Kabuto, even with overpay applied to the ~4.5 buds from the Chieftain.

So... yeah, iunno. Maybe I was just lucky.
