The latest dj tips controller guide gives both 5 stars. I have just bought the mc6000 from http://www.cleverboxes.com for £545 and its a beast of a unit that will take all the knocks. I would agree that build quality is the best of all the units and its got all the inputs and outputs you could ever need. Most reviews complain of it being cramped but it feels fine for my fingers. It has four physical chanels but is not as portable as the reloop. Denon have released new mapping to control sample decks and looping recorder in traktor pro 2 and are starting to advertise it as a pro 2 controller. At bpm I was impressed by denon, vertax and reloop from a build quality point of view. Although I haven’t got the experience of many on the forum, all I can say is I am not disappointed in the mc6000, maybe even more impressed than before. Everything will depend on the cash you have and the portability you need.
