I have an Anne Pro II, Magicforce 68 bluetooth thing(smart 2), Das Keyboard Ultimate 4, and, I think, a Keycool 84 2S and a Das Keyboard 4C Professional. I had a Cooler Master M and a Magicforce keypad, but I sold the two of them to a coworker for $40....I just couldn't stand to use them. I am trying to get rid of the 4C and the 84 2S at the moment. I despise the switches on the 4C and I hate the layout on the 84 2S. So, yeah, I have 3 that I plan on holding on to for a long time, but 5 at the moment, I think. The Anne Pro II, Magicforce 68, and Das Keyboard Ultimate 4 are the only ones that I have at home. All of the others are in a drawer at work.
