Oh, man. Mine was Denon MC3000 back in 2012. 5/5!
This was a purchase after a very careful study of the market. This little beast was built like a tank and had both balanced and unbalanced master out, proper mic channel, perfectly mapped controls for Traktor Pro 2 and pretty decent small jog wheels and pitch faders.
It also had plenty of Denon-esque extra buttons like pitch bend buttons that could be mapped with Traktor to do all kind of cool things. Man, I loved that little controller. I gave mine away for an upcoming DJ but to my knowledge it is still in usable condition to this very day
My upgrade after this was a pair of used Stanton t. 120C turntables which I still have and love
