Reply to Beginner DJ, Quick question.

So I've been into music my entire life and recently started to work on djing. Ive purchased a mixtrack pro and I have a new dell on the way. I'm using Traktor LE2, and I was going to upgrade to pro when I received my new laptop. That would cost around 140 or so to do with the code received from NI. However I've found out that right now the KX1 is shipping (or emialed) with Pro 2. So for less than 100 I could get the KX1 (essentially since I am planning on upgrading anyway.)

Just trying to figure out if this would be a worthwhile investment. I'll be upgrading from the mixtrack when I get better, but I feel like I want to stick with controllers. So is it a good deal for me?
