A lot of auto parts stores (Advance Auto, Autozone, etc.) will have them and I know I use to see them at Walmart sometimes. You can probably find them online at a store like autogeek.net...thats where a lot on here get stuff from. I know if any true Autopians (I'm a newb to here) reply they will say that you can't get any great results from machines like that. I had a 10in Buffer from Sears and there were times I would get some alright results, but I doubt it compares to something like a PC. I just picked up a Meguiars G110 which I'm replacing my 10" buffer with, so I'm hoping to get some great results with that.
