I've tried to get into contact with him, I'm a moderator and I was in this group buy. Other moderators have tried to get into contact with him, HELL, even the site administrator/owner has tried.
I honestly believe the parts that have been sent out were from the first order dave received. He said a while back that he had received half the package adn the other half was on it's way. I think the people that have received their goods, were goods from that first package.
Just my thought anyway.
