in my opinion (i have lots) the SM-3 is a very well built, although poorly designed mixer. The cross fader is usless you scratch and are very used to. if the mixer is not perfectly level the cross fader will slide across, even blowing lightly on it will cause it to move, making it next to impossible to juggle on(and its meant for hip hop!). it is imposible to tell visualy what is cued in the dark(important for drunken club DJs). no XLR mic input. the blue light is blinding when used in the dark(I can just afford to cover it with a penny). who uses TRS outpts? they should have used the standard XLR. the headphones don't crank like a proper(non-bedroom) mixer, you literaly need the V700 just to hear any thing in a club/party. further more, what kind of moron would position the EQs so that are not directly above the channel fader, it should be a little bit more natural. i love being negative!!!!! it sounds decent though and is the first well built Numark, also I think alot of my issues are delt with on the SM-1&2
