I just bought one of these to have displayed in my house (big collector of anything TK related). I got it Friday and started sanding, shaping, and painting it on Monday. I've done a side by side with my CAP that I troop in to see the difference in size, shape, etc. Personally, I like it. I know that as a 501st Member, I'm supposed to demonize recasters, rip-off artists, etc. but he actually didn't say anything about 501st approval or anything in the ad. It was a solid piece that I wanted to do as a project to see how I could make it look.
Personally, I would recommend you buy your first from one of the great members that build and make available super accurate buckets, not only to support our members, but the experience to build, paint and create your own first helmet. It would be your first step into a larger world
