I got PRM engine, and swingarm plates. I think I got a great deal. The prices were reasonable, shipping wasn't too much. I haven't test ridden them yet, but I am going to this weekend. The swingarm skid was 250. thick pretty much all around. The highest plate was 125. thick. The engine skid is 125. thick too, but that doesn't really get hit all that often. If you are looking for 400ex skids, then I would reccommend PRM.
