The new Dewalt DWP849X is the same weight as the Makita at ~3kg. It has the same RPM range as the Makita which is 600-3000 RPM. It has soft start and variable speed trigger too. There are some quirkiness to the trigger as experienced by some people. First it does not have a positive feel and gradual speed change as the Makita. Not sure if that has been rectified. Secondly, on free rotation, when pushing the trigger all the way down from zero there seems to be a slight speed overshoot before it settles down at the target speed. Might not be too apparent underload. The rubber insulation on the RB head is also a good feature as you won't really feel the heat generated if you like gripping the RB head. One thing the Makita runs a tad cooler than the Dewalt. Not too much difference in sound output between Makita vs Dewalt DWP849X. Both runs reasonably quiet in the low RPM range (
Do check if the Dewalt RB comes with the original flexible backing plate. The Dewalt flexible backing plate is meant for pads 6.5" and larger. It is high quality and better than the LC flexible ones. Just that you need to be accustomed running larger pads - most enthusiasts that I know tend to like 5.5" these days including myself.
