I have it narrowed down between the HD DA polisher and the Griots Garage DA. Have any of you guys had experience with either polisher? Or both? From the reviews the Griots has good cutting capabilities and an excellent warranty. However the HD comes in at a very good price point, and is supposed to have a more powerful motor than the well known 7424xp. I have very little experience with machine polishing, and I am just looking for something to get started and maybe do some detailing for money on the side. I have also looked at the 3401 but I have a hard time justifying getting something that powerful ( and not to mention pricey!!) right off the bat. Any feedback is greatly appreciated!
