I'd really like to see the K65 RGB show up on here. I won't pay full price for one, and I'd prefer they had any tactile switch (blue or brown) instead of just red, but for sub 100 I'd get in on the drop.
Blue's are short because of manufacturing issues. Many consumers have complained about the blues not feeling right, or feeling like browns, no clicky sound, etc etc. Shortly after, no more blues were shipped. Dunno if it's corsair, or Cherry messing it up, but that's essentially is what's going on.
