Skids..
The EST125 and DTS400 have a lot of the same specs.
I find the ETS125 removes more material faster then the DTS400. The DTS400 is nice and smooth in operating. By that I mean it doesn't jump around
like some guys say the Rotex sanders do. The DTS400 with 40 or 60 grit paper on it will get down and dirty for you. And you can keep it under control.
If you're looking for an opinion, I would get the DTS400. Since you already own the RO125. I only wanted the ETS125 and DTS400 to fill my Festool
sander wish list. But the recon sale happened a few months back and I used that as an excuse to buy the RO125

. Which turned out to be
another slippery slope for me, now I want a couple more Festool sanders.
