Ok ... So I am still looking around at what type of polisher I want. I was initially considering a PC but im now leaning more towards a rotary. Ive always been partial to Dewalt power tools but im not so sure about the polisher. The reason being Ive used the makita rotary before (borrowed) and I liked the ability to control the speed with the dial. So my question is how easy is it to control the speed with the dewalt? And how do you know approximately how many rpm's youre at? Thanks!
