Reply to Reloop contour, ideas/reviews/cons?

I was browsing the internet for a digital dj setup.
I found the reloop contour IE.
So here it is, I'm quite new to the digital djing scene. I've been looking around and browsing the internet.

my idea:
run a laptop with traktor for basic djing (small party's, small gigs) with 2 reloop contour IE and a (digital) four channel mixer in between.

And later when it's all working and I wanna kcik it up a knotch I'll introduce ableton and combine them. (bigger gigs, live producing and musical performances)

I know this is a lot to handle for one person so there is a little side note:
I'm going to be doing all of this with a friend of mine. (except some of the small party's.)

I'd like to hear your thoughts, comments, pros, cons, reviews for the contour and corrections in my english.

thanks in advance!
