I have a reloop digital jockey 2 and 2 reloop contours, The dj2 is pretty low end, although the best low end controller I have seen, but the contours are great quality, the only issue I have with them is the leds on the top four encoders are a little difficult to see unless you are a lot taller than the table it’s on or the controller is on a slight angle, apart from that great knobs buttons are good, there is 5 hardware shifts built into the jogs for some crazy mapping possibilities, there is shifts for the decks and standard shift functions, so even using traktor you would have a lot of options for mapping, the contour doesn’t have any sliders to judge, but the the DJ2 has a fantastic crossfader, but crappy line faders. Overall the contour is a great controller and being the baby brother of the DJ3 is probably a good barometer for the quality of the DJ3.
I would definately wait till after NAMM as there may be better controllers released, but there may also be a significant decrease in price as the DJ3 will be older technology next week…
