I had the Dewalt
Buffer/Polisher, Variable Speed, Soft Start, 7-Inch/9-Inch (DWP849X) and I returned it, it was huge and too heavy. I like polishing, but the Dewalt is a backbreaker. It's almost 7 pounds and I'm not getting any younger. 600-3500 OPMs, and a 12 AMP motor. Don't get me wrong it's a great tool just too heavy for me, and I'm not tiny I'm 6'2" and 200 lbs. just my arms were beaten after polishing up my boat all day.
I'm looking at the Griot's Garage G9 RANDOM ORBITAL POLISHER, it's around 5 pounds, 2000-6400 OPMs, and an 8.5 AMP motor

The Surhold is 4.4 lbs. with a Variable speed of 2500-6500 OPMs and a 4.2 AMP motor.
My cousin and friend do bodywork at a shop and they both swear by the FLEX
L 1503 VR, it's german made, it's light but expensive - $300 plus, 4 pounds, 1200-4900 OPMs. They both said lighter is the way to go on these.
I haven't pulled the trigger on any of these yet but spring is coming and the boat wrap will be coming off soon. I don't want to spend $300 plus on this would love to stay around $150 for the Griot's or the Shurhold just can't make up my mind.
