Reply to Numark Turntables?

Ok im getting ready to get some tables to accommodate my S4, and i was looking at the TTX1 and i realized they are kinda hard to find for some reason but the USB version is easy to come by. Some reviews say the USB version is good for scratching while others say it sucks for scratching and is only good for mixing. Im looking for something decent to scratch on but mostly mixing. Ideas?
