It's 20 bucks now. http://www.solidice.com/

But, as others have said elsewhere it's the best 20 bucks you'll spend in your multi-boxing investments.

I spent well over a grand just upgrading my computer and haven't been as happy with the results as I was by dropping my money on keyclone. Without keyclone I couldn't multibox no matter how much i spent on hardware, with it I can multibox on any piece of crap computer I can install it (and wow) on.
