The Skynet Edition looks like garbage. It's almost as bad as the "Ultimate Hunter Edition" of Predator.
Haven't seen any T1 Blu-Rays, so I don't know how they look.
I rarely buy new from a store unless there's a sale going on, or it's something I have to have right away (very rare - Blade Runner and Apocalypse Now are the only two that I've done this for so far). I get the majority of my movies from the used section at FYE, or from Reckless Records (all used).
