Reply to Wanting to start mixing.. (on a tight budget)

Afternoon folks, I've read tons and tons of threads on this community , the wealth of information on here is amazing. But I must admit it's only made me more confused!

Basically I want to try my hand at mixing, I've been involved with music production as a hobby for the past 10 years so I'm not completely new (in fact I've got the concept of mixing down relatively well in the past couple of weeks messing about on Traktor).. My next step is figuring out which controller to buy

I'm looking for something that has a built in audio interface, I have a decent soundcard on my main pc but I plan on using it with 3 different pc's so I'll need the headphone monitoring out on it. I'll be very honest, I will be mixing using cue points and sync so a jogwheel isn't neccessary but they all seem to have that so it looks like a must.

So far it looks like the Numark Mixtrack Pro II is perfect (in terms of functionality and cost), but I was just wondering if there's anything else I'm missing?

Also, since I'd be using cue points I had considered a Traktor Kontrol Z1 and Launchpad mini combo (since I'd also be able to use the launchpad in Fl Studio).. Are there any downsides to something like this?
