Hi Frosty,
Let us know what you end up with...I'm kind of poking at a new controller as well. My beloved Alphatrack is making some strange noises these days and may be getting a bit long in the tooth. I'm thinking about a touch screen, but I'm worried about control precision, particularly on faders. In any case, I'll be interested to hear what you end up with.
Incidentally, I did look at the SSL Nucleus but it includes audio I/O and I'm pretty modular around here these days and don't much want to change.
Oh, and BTW, while I'm certain that Freddy has a great facility, the photo he posted that includes the Duality isn't it. That photo is of Vanquish out of Florida, and you could probably visit there easier than Sweden.
