The Super Programm (SuperA in Europe) is only a improved version of the ME/MEsuper, just more electronic and a faster shutter.My guess is that you would only see 3 real advantages to the SP. Shutter is 15 to 1/2000, it has TTL flash capabilities, and it can accept a winder or drive. (It also has shutter priority and a program mode - both of which I regard as not much different from aperature priority).
I don't think the SP's finder is as nice as any in the K-series, but it does offer more eye relief.
There are a lot of SPs out there. Pick one up some time and see how well you like it. My SPs are not much louder than my KXs, but at least one person here (William Robb) has convinced himself that the SP has more mirror/shutter vibration than many other bodies.
These shutters more recent than the K2 and present less vibrations and noise.
