Paasche VL.

It come w/ 3 tips/needle combinations to handle anything from watercolor to latex. You can also get up to a 3oz jar for it (great for holding thinner/cleaner). It is a dual action brush w/ very good control. I've had one for over 20 years & never regreted it for a second. I can spray anything from 1/32nd" line to about 2" pattern.
