Interface for DJing and production: komplete audio 6, AK1, scarlett 8i6, etc

I'm looking for interfaces that are about the size of a small brick with plenty of inputs and outputs to use for both DJing, production, and in-between live-production. I am most interested in the komplete audio 6, but am also considering the AK1, scarlett 8i6, and other saffire interfaces. Must be USB, as I am on a PC. definitely PM me if you have an interface that might work.
