i had the previous mixtrack and tried the new ones but i have to say the "drum pad" buttons took a lot out of the controller. like where there were 12 buttons theres now only 8 and these were the kill buttons and loop buttons. i traded it towards a 4 trak, but since your set on Serato id say get an ns6, much nicer feel, and native to Serato and comes with a version of Serato if im not mistaken. pluse they are getting to be plentiful since everyone is now trading them for the ns7, while others are trading ns7s for the ns7II.
