Would either of these do the trick in a budget?

The ATD 10511 7" rotary, or the craftsman 6" rotary? My car has some defects that the PC with 83 is simply not getting rid of and I need to step it up but can't afford the Makita. I have already tried Scratch X with a ton of passion and that didn't work either. Has anyone had/heard anything good/decent about these?

Do not get the Craftsman OMG! i bought it, thinking i would save some money, but i ended up breaking it before i even began to polish. The lock mechanism is ****, it ended up grinding the gears. I just bought the dewalt and freakin love it. worth every penny.
