I'm looking at getting a buffer system. I know alot of you like the beaul system. I looked at a nice 6" variable speed buffer with 2 heads the other day and was wondering if this would work for me rather than the beaul (the price is about 1/2). How many of you use a buffer and what would be the advantage or disadvantage of either one? It looked like you could change the wheels easy so you could have a 3 wheel system.
