Cougar 450k waterproof keyboard

I had a few times where I spilled my drink on my keyboard which was a buckle Springs keyboard. And once again I have to wait to get enough money to send it back to get repaired. I'm currently looking into this cougar keyboard and would like to have it. I know I wanted the bloody keyboard that was at Computex, but I would like to have the cougar keyboard instead.

Does anybody know when this keyboard is going to be on sale and where?

Why not waterproof your current keyboard?
