Dawn of the Lead posted up an article reviewing the A.T.A.C. APC from Scotia Grendel.
From the article:
Overall verdict: Apart from some casting and size issues, the A.T.A.C. APC is a very nice find for its price. It’s not perfect as a model or as an Aliens APC proxy, but if you want a little armoured power for your troopers, you could do far worse – especially if your minis collection is more 28mm than 30mm.
