I sent an email to some of you about this, but I thought I'd post here as well. I received a reply from Bob over at Imprint and he says he's still in business and isn't sure why no one has been able to contact him. I've asked about discount bits for a BMP-3 and the hummer (DaveV was interested in a few of those).
Britain seems to be on the verge of financial collapse, so it may be prudent to order some things from Bob before his credit dries up and he can't afford to buy the resin anymore! :P
