I bought the Blue Switches version, and I really like it for typing (at work).  I want to try the Red Switches for gaming, but I hated Black switches when I tried them a couple years ago.  They were too stiff and not having a tactile bump just felt "wrong."
Still, I wonder if the lighter Red switches would feel better when gaming (and maybe the lightness will hide the lack of tactile bump a little).
$100 shipped is still about $20 too much for me to take that gamble, right now.  If I could get it for $80 shipped, I'd buy it in a heartbeat.  Even $90 shipped would be a lot easier to jump on.  Things just 
get real when it goes to $100.
