All depends what you want tbh,,,the festool and mirka are a joy to use, both will do the job in a fraction of the time, with a vastly superior finish,,they also have anti vibration etc built in, so no numb hands,,,dust extraction that works, so no breathing the stuff in,,covering your work area,,or more importantly grinding it into the bat,,this is a huge part of achieving a decent finish.
You have to look at the sander orbit,,this is important for the finish,,,lower is better, but won’t remove material as quick,,hence why festool have the rotex.
Honestly I wouldn’t waste my time using anything cheaper than the dewalt,,,it’s not worth the hassle,,
It has a low orbit, built in anti numb hands and a half decent bag for the dust if you don’t want to use a vac
Just to add to my earlier point about only using 240 on refurbs,,,,that’s on bats I’ve made
I charge a little more for other makes based on how poorly I find the original finish, and the extra work needed to sand out marks etc
