Minor update, Massdrop have shipped the Gateron switches. This is for the slightly cheaper option, providing you submitted the form before the 17th of April. These people are: liillliillliiii, B1G_B1RD, jo do, and FlakeTwist.
I currently have B1G_B1RD, uberweasel, feeder, SRTroN (Reddit), TheMissingPiece, TerryMathews, and maximm interested in anodizing. The anodizing people haven't replied to my most recent email so we're waiting on that.
