Reply to Pioneer DDJ-T1 Audio Interface Usable for Production

I'm really believeing of getting the pioneer for mixing. But just wondering could the in built audio do as good a job as my fast track pro. I'm producing using logic on the mac. I also do a bit of podcasting, but believeing I could use the microphone input on the pioneer to keep on recording that. I just want to know everyones opinion and is this a good idea or not. Obviously the fast track pro is small, but would mean selling it I could get a little more cash towards the pioneer.
