Reply to Gear oriented MF questions

I've been asking questions about various ways to get going with the digital DJ route and this is in my thread in the general discussion community , but I thought that it might be better asked in here, if that is against the community rules, I apologise in advance...

I just watched the midifighter mix on the front page (the one where Ean is using 2 midi fighters that starts with the rage against the machine song) and man that really made me itch for a couple of those, with that in mind things might get quite a bit easier on the gear side of things, so real quick

A) what is the mixer that ean is using, and is there a 4 channel equivalent

B) what would be some nice 2 and 4 channel mixers/controllers that work well with traktor

C) could I still go timecode and controllers with the 2 midifighter setup

D) is it possible to go full on with it and get 4 midifighters (one for each deck in traktor pro) all while running the whole thing with 1 4 channel mixer/controller, I imagine that could be some true madness (or I could get overly enamored with all of the buttons and make stuff that sounds like total shit, but I believe the things are slicker than whale shit)

Again thanks to everyone that has taken the time to help me out
