I was torn between so many different DA/random polishers.
I was looking at cordless first (to do my boat) and I already have Makita drills/impacts.
The Makita forced rotation is amazing in the forced rotation setting, but it can also free-spin random orbital but I guess it stalls faster than other DAs.
Flex has some really good polishers, right up there with Rupes.
Some of the better cheaper polishers (from my research) are Griots and Maxshine. The smaller throw orbit Griots is like $150 so that is a great buy for the price. Once you get to the larger 15/21mm throws then they start getting expensive, which pushed me into the Rupes LHR15.
