That particular supplier only has 3KW spindles in stock which would be silly, and I was a bit confused that they are being despatched from "CA, United Kingdom". Based on my experience, if you want to go for a water-cooled spindle (much quieter and better for long runs than a simple router) I would go for the smallest model as being better matched to a timber-built machine. Limited collet size but you aren't going to be able to use large cutters anyway.
OK so OTT is the general reply so far. I'm hearing it will shake rattle n roll my parts of my machine.
I'm looking for a spindle that will carry with me to my next stage. 1.5 k.w. - 2+K.w. is my thinking.
I don't mind the spindle killing my current machine as long as it teaches me what to make stronger on the upgrade.
