I want to buy a polisher this weekend.:xyxthumbs I can get the Porter Cable 7336 Polisher at the Lowes by my house for $99.00 because it is on sale right now. The only thing that i can really see different between the 7336 and the 7424 is the the 7336 has a dust collection system. Am I right about that or is there other things that are different to? Or should I just wait and order the 7424 offline? Thanks for your help who-ever replys!:up :xyxthumbs
