There are several options as im sure you know. But I like these 3 for various reasons.
With the Stomp IO you will not only get the controller but all the Amplitube products. then buy a couple of single midi volume/wah pedals and you got it. Thats nice because you could position the volume or wah pedals away from the main pedal. The Stomp IO is pretty much like the Eleven Rack, as it is also an interface.

and finally........ thats right BEHRINGER
Sure they make some sub par things, but this is just Midi info being transfered. Its hard to mess that up. The pro is, its cheap, and you got lots of pedals, con is its not as sturdy as the Roland or Stomp, but if your not jamming your foot into it like you would a red headed step child
it will hold up fine.
