I might be buying one of these sooner than I thought. My really cheap router stalled today for no apparent reason, and emmited a little smoke. It still runs, so the motor is fine but I think the collet chuck is damaged. It's not holding the cutter on centre now.
When it stalled I couldn't stop everything fast enough so it bent the 8mm steel bar that I was using to extend the length of the cutter - shows how powerful the steppers are to do that!

Anyway, I think I'll get this one from this seller:

It's the cheapest I can find. He's not got much feedback though...

Maybe get a 2.2Kw one:

Or is that overkill?

Does anyone here have a dimensioned drawing of one of these spindles? What does the 180mm length correspond to exactly - as in does it include the chuck/wire etc?
