Good point but I think most of those oopsies were the rotary edge spinning against some plastic, I've done that a few times,, enough to scuff up the clear anyway. With a good polish like the 1&D or Megs 101, I'm getting fingernail catching scratches handled quickly, almost scary fast. And this is all talking at a hobbyist level. If you are a pro, absolutely, the fastest machine possible is the right answer, it pays for itself quickly. For hobbyists, its just another step up the ladder of gratification followed by want for more.
