I also think the print on disc 2 is the best one I've seen so far,only checked out the others briefly (for now) though.
I also still have the audio commentary and Scavolini interview (my Italian is ok-ish) to go .
Good retailers for CR stuff:
Planet Axel most titles that are listed as "pre-order" are in stock btw!
Amazon.com DiabolikDVD Video Universe
Or you could also try Amazon UK,seems there's also lots of Code Red (except for the new(er) releases I think).
