I'll second (third? fourth?) the notion that you'll want scribble strips for anywhere you're using multiple pages. The Producer seems to hit a fairly narrow market: Somebody who needs physical faders, to fit in a rack, and doesn't have an extra $1k to get the M32-R. Anybody who isn't fitting the board in a rack should get the compact for the scribble strips. Anybody who needs rackmount but doesn't need faders could bump down to the x32 Rack and a tablet. On that note, I run Android. Since Behringer doesn't make an Android version of their app, I've found the Mixing Station app invaluable.
