Just a heads up. I visited the MicroCenter in Tustin, CA today and they dont have demo keyboards to test anymore. They're all inside their packaging, on the shelf.
One of the guys I spoke to told me people would steal them. Sucks because I really wanted to test out a Cherry Brown before I settle on a keyboard (leaning towards Clears).
They did have a Cherry Blue keyboard to test (Vengeance or Trigger, I forgot) because of the cut-out above the arrow keys.
Anyway, I remember 5-6 years ago they used to have keyboards sitting out in the open, but of course, at that time mechanical keyboards weren't popular.
