I've always been interested in the Siemens CNC controls.. Never used them but I've heard a few good things about them.
I don't know if anyone here actually has or uses them but I thought I would toss in a few quick links to them if anyone is interested.
I am already considering one of the 802's when I go to get a new CNC.
The Sinumerik 840D

This is but a few pages of their site..
Their site is pretty helpful and the manuals are downloadable.
