I recently bought a set of ps2's and a q-mixer. So far I'm only half impressed because one of my players doesn't cue up on its own. You have to hit the scratch effects button to get it to cue up. My search knob doesn't work. The pitch percentage only changes when "it" wants to. The only thing that will impress me is how fast they can get it back to me when I overnight it out and if it is permanently fixed. I've only had this system for a month and it started having problems the first week.
