I like the Binks HVLP guns in use with the binks pressure pot. The Sharpe 775 is a nice gun not to high in price and has nice spray pattern. the old trusty is always a Binks #7 best all around gun. the Binks 2001 HVLP is my gun of choice. your finish is only as good as the gun you use will allow.
cheap gun = poor paint job
