Have you considered the UC1 - hands on control of SSL channelstrip (4000B or 9000E/G) and bus compressor plugins?
I think it's such a wonderful complementation to a DAW controller like S1 or in my case 2 x Artist Mix. You could sell the S1 and have the UF8/UC1 combo, but then you would not have Eucon. But a S1 + Dock + UC1 = Dynamite, IMO.
UC1 – …"from my cold, dead hands".
