I current have 3 dual action polisher (Boss G15,Flex 3401,Rupes Mini) and been wanting to add a rotary I never used one but got a parts car I can practice on I was looking looking at Habor Freight and seen they have a Drill Master Rotary #60626 for $30 with the coupon so I was going to pick that up just to practice with a rotary and after I start getting good enough experience with it then move up to a quality brand rotary?
