Since it was asked, I'll weigh in a little on the Coyle and Tomenosuke blasters. Darthwolf and CessnaDriver explained it pretty well but there's always one thing that really grinds my gears when it's mentioned....
Most of us are aware the time and effort Rich put into the research of the blaster and his history. He deserved a lot of credit for his contributions and I believe he's received plenty of that. I absolutely mean no disrespect to him because he has put in the hours and produced a great kit, and updated dated it several times. Us Blade Runner fans have benefited greatly from this. However, It's been noted here, and many other times (by Rich himself, especially) that Tomenosuke and others "copied" Rich's design. While Rich and Karl were on site to view the hero prop, so too, were the Tomenosuke team. They spent a lot of time with it as well and took their own photos and certainly performed a lot of their own R&D which did include a much earlier version of one of Rich's kits. If memory serves me correctly they even sent Rich a blaster as a sign of gratitude for his contributions to the Blade Runner community. How much they "borrowed" from his kit is debatable but that is why you have several versions now, just like Rich's. When new information comes out, or the production team realizes there is room for improvement it will be updated and released.
I don't need to re-explain what CessnaDriver already stated regarding the two because I think that's an accurate representation of how I feel about it but what I will say is that personally, I prefer the Tomenosuke Blaster for its cleaner lines, Rotating cylinder and overall quality of materials/production value. You do have more metal on the Coyle, but I'm ok with the hard/heavy plastic barrel of the Tomenosuke. Plus it's at a better price point, and while I understand that's achieved by having a production facility produce the blaster, that's also an important selling point for me. The Tomenosuke is a solid piece and feels like a real firearm. It has great weight/balance and just feels great in the hand.
I watched the video and while I changed my pre-order to a kit from the assembled model I don't mind the flat black of the receiver. I guess I imagine this piece as an "as issued" police blaster and not a copy of the hero blaster so much, that's what the kits are for!
All in all they're both great blasters and you just have to decide which one fits your preference more!
