Oh 3M and your name confusion! They've got 2 product lines with the same name since they acquired Accuspray themselves. Do you mean the Accuspray 10 guns, or the actual Accuspray system with the little plastic nozzles? The system seems to be getting pretty popular in the states by all accounts.
I'm using the 10G Accuspray guns with a Turbine, the ease of finish is fantastic, I wouldn't be without them. When 3M bought the company though, they screwed up the availability of spares, which are still a problem to get in Europe.
