I agree with everything you said about Zandar and SAW Viper, really enjoying those figures, Leatherneck didn't really stand out in anyway for me. Possibly becuase I never had him in the 3.75 when I was a kid. Nothing wrong with the figure at all, he just didn't POP for me. I am still waiting on Dialtone, I had my order with Amazon cancelled, and I am still waiting on Walmart to give me a shipping date.
Amazon sucks for pre-ordering - Dial Tone was the 4th figure that I pre ordered, and that they canceled after the shipping date.
