The types of use will influence choice. Light protein,
erasing abrasives use lower pressures, while fast cutting,
etching types require higher pressures that are not usually
available from hobby compressors.
Having sold airbrushes since 1969 and used a Paasche Air
Eraser since 1971, I rate it best. Others do not have as
fine a spray pattern. Steel nozzles are quickly eroded by
sharp compounds, while the carboloy tip lasts very well.
Siphon feed does not work well with heavier abrasives.

accessories see first site below.
Hope this helps.
