I am going to buy a polisher and have semi locked in on the Rupes 21 Mark II bigfoot. can pick up a nice kit for $570.00 shipped. I am just a weekend warrior and have a gen1, gen 2 (sons) my work truck (16 Colorado) and the wifes explorer to take care of. I am a tool junkie and like to buy quality the first time so I know I could get by with a lesser polisher but don't want to regret not buying enough tool down the road. Has anyone used this or what do you use and recommend?
