Air brush I use is a Harder & Steenbeck, Infinity with a 0.2mm needle for fine detail and a Sim air XL 2000 with a 0.4mm needle for bulk spraying, I bought the Sim air cheap as the two glass jars was cracked , but it all so has a side cup and this model has the same inter changeable needle nozzle set up with Harder & Steenbeck Infinity, as far as the jars I got lucky I found some old bottles in the back shed same size thread and slightly larger, crack bottles 15cc new bottles 22cc
The Infinity is over the top for what I use it for, I have learned the hard way, some times its best buying quality then cheap.
You can buy Harder & Steenbeck Evolution - Two in One for £120 with a 0.2-0.4 needle set up.
The compressor is from
http://www.everythingairbrush.com/acatalog/AS_Series.html and model is an AB-AS189 Mini Piston type "0n-demand" compressor with receiver and Dual Switch - For Airbrushing Ref: AB-AS-189 Cost £95 and are quit.
My last compressor run like a car with no exhaust, wife was not happy, but I took the 6 ltr tank of and connected it to the new compressor, so I would have a larger volume of air to work with before it would restart.
