Reply to The Pioneer DJM-T1 mixer

Hello everyone!
I am new to this community , so excuse me, if I posted this theme on the wrong place.

I have decided to buy my first mixer, and I fell in love with the pioneer latest DJM-T1 Traktor compatible mixer. Now I have been mixing for some time with DJ Traktor, so I believe that this is a perfect match for me. But however I have some questions:
1. Can I use this mixer with the latest Traktor DJ 2 (http://www.youtube.com/watch?v=eJQjaQ6rWpw)?
2. Can I use this mixer without the twin decks?

I am limited with my money reserves, so I would like to buy mixer only first. Could there be any problems when mixing? I was believeing about it, and basically you don't need the twin decks for playing the music, because it is all on the hard drive. I am going to buy the decks later, that is for sure, but now I don't have the money.

The problem when not using the two decks is the beatmatching. I have been using the sync button so far, but yes, I had some problems. Never the less, those were only small problems, and the were easly covered with effects. Could I perform using only the laptop with Traktor DJ 2 and the mixer DJM-T1, or do I must have the twin decks?

I have been also believeing about the two different options:
1. The new Pioneer Traktor compatible controller, DDJ-T1.
But there's a problem. I will have the controller probably only till I am able to buy the full set, that means, that later on, I would have to sell it. Not actually my style.
2. The 2xCDJ & DJM 350 set. A great thing, especially for the beginners. But the mixer isn't compatible with Traktor, and that means a lot less effects.

Now, when I buy something, I intend to keep it for some time, that is why I would like to buy DJM-T1 mixer? Could I perform on gigs with ONLY the DJM-T1 and the Traktor software or not (that would last for a year probably, then I will definetly buy the twin decks)?

Thanks for your help!
