I hope our right about people chiming in, I am trying to decide on which one to get myself. The two main choices out there seem to be the Porter Cable 7424 or the Cyclo, the main diff. that I have found are, Price - the PC is way cheaper, but the Cyclo works the product better and allows you to apply more pressure to the surface if needed. Both are random orbital and have been deemed "stupid proof" by 99.9% of the people out there, what I mean is, by using one of these it would be very very hard to burn your paint. However I have also learned that if you have really damaged paint you really are going to get a better effect with a rotory polisher. HOWEVER, these are pretty much reserved for pro's or at least very experianced (sp) users and one should try and practice on something besides your good car!!
