Okay guys, I think I'm going to venture into the world of the rotary polisher. At this point, I just want to use it to polish windshields with something like the Diamondite kit. At some point I'll probably get some panels from a junkyard to practice on but not right now. Anyhow, I see I have quite a few choices ranging from Dewalt, Makita, and Flex. I think there are 3 models of Flex rotaries. So, what would you recommend? Bear in mind that I've never used a rotary before and know nothing about them. Cost isn't a factor by the way.
