I would definitely want to get my hands on a full size griptillian 551 with a tan or black handle. Also what I suggest is purchasing a bulk amount of the knives based on the most popular variations, and then offering them up through the MD Shooters web store.
If this is dead, Joe Bob has Benchmade 556 Mini-Griptilian for $80, throw in a pmag or two for free shipping and a free t-shirt. We could even see if someone could do separate engraving.
