Nevermind… Looks like its still heavier than the DeWalt. Still thinking about it though, mainly because the DeWalt + speed regulator comes to about $90, so maybe its worth an extra $50 for a purpose-built spindle?
Is there a distinct advantage of brushless spindles? I’m seeing a lot of 400W brush less spindles at around the $200 mark with the corresponding power supply and driver. They’re listed as around 2 lbs, which is the lightest I’ve seen so far.
