Just thought I’d drop you all some rather pretty links. Pig iron productions is a small miniatures company who have slowly but surely building up their selection of models. The most recent and damn good-looking of these are in my opinion perfect for alternate IG models.
firstly the "kolony" troopers, ideal for steal legion or death corps
and second the heavy infantry models they produce, storm troopers anyone?
they also produce a tank (with APC, Armed APC and mbt versions) and a line of wardroids.
Their full range can be found
