I own a Model 1 (http://playdifferently.org/model-1/). The overall feel is very "analog" and the faders are by far the best I've ever used. The "filter" approach (LPF,HPF) is also hard to live without.

With that said -- not going to lie, still remember the sets I've done on the Radius 4 or Rane's. The feeling creates a totally different experience and it changes the way you mix. Casual, fun - "closer" to the audience somehow.
