Kromlech easily has some of the best alternative orks on the market. I've been steadily building up my collection of them to form a Blood Axe army. Primarily built around the great coat orcs and tank bustas. I recently picked up this 'command squad' which includes the Warboss, Waaagh Banner, Big Mek and Weird boy. The figures are absolutely amazing, especially the warboss and waaagh banner.
