I have Ryobi for that. Got it with a drill, and have since bought a couple other One+ things. I did have a look at the Milwaukee stuff when I first looked, but unfortunatley I decided to save a bit of money and went Ryobi.
Now, there is nothing specifically wrong with the Ryobi gear. The stuff I have has lasted years now, and I actually like it plenty. However, when recently looking for a wireless DA polisher, the Ryobi one didn't review well at all. Where the Dewalt and Milwaukee do make some pretty decent car polishers now.
So now I wish I had gone either Dewalt or Milwaukee from the start, as I am now juggling 2 different battery systems. It seems sub-optimal to sell the Ryobi stuff to replace with Milwaukee at this stage, especially for how much I use them. But it would have been better to just have spent a little more initially and got into an ecosystem where all / most of their tools are genuinley among the best rated. Even if for nothing other than I;d already have the batteries, and so could have just bought the bare tools when I decided to get the polisher.
So, with that said, you may not be thinking of the next tool you might buy in a few years time. That tool may not even cross your mind here. But look at the complete system contents would be my advice. And all aspects of it. The Milwauke battery system for example is arguably a little better than the Dewalt system (and so that's the way I went for my polisher). Look at the battery prices too, not for the 2mAH batteries you might get with a basic kit. But for the 5 or 6 mAH batteries you will probably want to buy a few months down the line. And the local availability for such things. You don't want to be a weekend hero, realise your batteries have failed, and have to wait 3 days for a new battery to be delivered when you could just drive 5 mins down the road and get one for a different brand.
