Just found these and have bought 4 boxes for £30 (this includes delivery to the UK!!), which will make 2 squads of 4 and each squad will have a unique looking plastic model. As opposed to GW's £160 for 8 models that look the same and are made from failcast.
As soon as they arrive, I'll try and find a "real" grotesque and get a pic side by side.
You may love me now
