First off, regarding Original Stormtrooper, owner Andrew Ainsworth is not the sculptor of the original Stormtrooper helmet. That honor goes to the late Ms. Liz Moore whose work Ainsworth despicably plagiarized. Helmets coming from his "original molds" look skewed and warped when compared with the screen used ones, and RS Propmasters is by far more accurate as far as Stormtroopers go than Ainsworth's.
Moreover, Ainsworth's Stormtrooper armor was created by illicitly copying the armor of an RPFer, so on the basis of plagiarism alone, I do not recommend any self-respecting prop collector support his business.
I honestly don't know what's more sad - that he continues this "Original Stormtrooper" angle, or that his misguided fan base are so starstruck that they offer props to him that he historically had never come in contact with for him to turn into his own products, unless he scoured around for something to recast on his own.
Lest anyone or Ainsworth himself accuse me of bias because I have sculpted Vader projects, I encourage you to visit The Prop Den and study up on Vader before you impulse buy and regret your purchase. There is a variety of vendor merchandise out there that many end up with buyers regret over. Please don't make the same mistakes we have made - me especially.
There is a bad loss of detail with his Vader, and an inaccurate paint job. It looks to me personally like he used something like a Don Post as a starting point, and at approx US$760, yes, I agree with what's already been said so far. You can get far more bang for your buck.
