Last week I bought a Gordius Little Giant 2.
To me that is the best controller for 11R (or any other fx)
Totally programmable. Not to big, very good build quality and a very, very good customer support. (I mean really good!)
Also the manual is very good. (with examples on how to program it)
and there is a pc editor. I was told that the mac editor is on it's way.
bottomline: small company -> great service + great product.
