Hi Tim, I have a Harder & Steenbeck Infinity 2 in 1 which I bought for those very reasons back in 2012. Ended up using the 0.44mm needle most of the time, but if you need finer there's a 0.25mm needle & nozzle combo too. I know they are expensive but it's my only airbrush and has been worth the outlay after all of these years. Well built and easy to clean with parts available locally to me (Edmonton, Alberta, Canada)
Good luck with your hunt, and cheers!
