Schielenkrahe, you're bang on with your E'Pro analysis, although I'd say that the professional appearance and craftmanship of the E'Pro is what really does it for me - The Pro actually looks like an instrument, whereas the Standard looks too much like some bizzare sort of homemade radio or hatstand than an actual instrument (forgive me, Bob Moog!).
One thing I appreciate about the E'Pro however is the playability across the whole range - on the Pro you can really exploit the lower and higher registers in ways that you simply *cannot* on the Standard, either by using the register selector, or by exploiting what is undeniably a superior playability in the upper and lower echelons of the instrument's range.
