If you want a high quality clacky mechanical keyboard, this is the one. I have one of mine hooked up to my Quicksilver2002 using a belkin ADB adapter. Love the sound of it when my typing gets some speed up.
Darn. I've got one of these. Came with the 8100 that I was given July a year ago. But I never get to use it because it's so big and I always need the desk space. :O
