Really interesting new company called Gang wars - well worth a look for those into Necromunda.
Its quite interesting that its taken this long for a company to use shapeways to produce full figures. Theres been a few companies doing starships and 6mm/15mm figures for awhile.
There offering a range of stuff including lots of weapons options (which, I should imagine, will work on imperial guardsmen as well as this range). The actual ganger options seem a little limited currently but the trench coat chicks are absolutely stonking lovely, and I should imagine we'll see more of these sooner rather then later.
