The main differences between the two are: The ME super only has the basic K-mount, while the Super Progam uses the KA-mount (those contacts on the mount itself, The ME Super has a simpler hotshoe, the Super Program uses a TTL communication for the hotshoe. The ME-Super has Aperature Priority, while the Super program has both program mode (giving control of the aperature over to the body), and aperature priority.
I'm pretty sure that's the main differences between the two, aside from builds, ergonomics and other details.
