My first airbrush was a Paasche H, which I bought about 27 or so years ago, I still have that brush, so far the only thing I have replaced is the seals once (probably didn't need to, but it spent 15 years stored in a unheated unloved garage in a wet climate) and a bent needle (my fault). I still have that airbrush, I will probably never get rid of due to modelers pack-rat-itis, and sentimental attachment.
It has been replaced by a Paasche VL which has actually seen little use, I kept going back to the H, as it was easier to master, and three Talons (one siphon feed and two top feeds) but if I wanted to shoot a fast monochrome colour or doing big areas (think model railroad scenery) I would reach for it before any of the double actions, once it is set, it is just blast blast blast.
So the down fall of the H, is that you have to stop and adjust your spray lines, or do ore masking, not a big deal really and it all amount to more practice. But you definitely would not be "under gunned"
