I'm trying to decide which is the best PKD out there. I know there are lots of ways to go.
I'm sure you'll get a lot of different opinions on this, but I think Rich Coyle's new 'Worldcon' version looks fantastic.
I have one of his v.4.x models, and if I could afford it, I'd upgrade.
As for the "best" PKD, man it's all opinion. I like my hartford models because they fire "blanks", and I love my Coyle blasters because they are cast from the same models of guns used to make the screen hero. I love the Rick Ross blasters because they are affordable, and loads and loads of fun to build, and Rick has such a passion for the film, he sculpted and created his own masters from screen still, and a paused VHS version of the movie!
That's bada$$ in my opinion.
