Wow...look what a quick Google search turns up:

Steelseries Sensi RAW meets those requirements and is similar in size/shape.
It has LED's on the top, but they can be disabled. Requires the software though (at least once).
It isn't black. It has a LED visible from the top. But thanks.
Looked black to my eyes. And you stated the MS Intellimouse Explorer 3.0 and that's what that was so you should have already known about the LED.
- without any LEDs on top, not requiring it's own software install and preferably ergonomic along the lines of an MS Intellimouse Explorer 3.0...
you want the Zowie FK1
Well, I'm looking for an ergonomic right-hander, but it's comforting to hear that you have good experiences with a Zowie product.
Do anyone here know how hard it would be to open up a Zowie EC1-A and disable the LED?
