Multirotor.co has some nice motors, but check out the price on the model MT2814-10 and MT2814-11 here: http://www.multirotor.co/index.php?cPath=2_56 Do you think those prices are typos?
DOH! That makes more sense. Thanks Mike. That doesn't make sense. Maybe the individual motors don't come with the "X" bracket and propeller mounts? Their English could use a touchup.
