Well finally took the plunge and bought a new airbrush. After looking on here for peoples views on good airbrushes, availability online and the fact I had an Amazon voucher given by my company for christmas I got this.
It’s the Harder & Steenbeck Ultra with two needles (0.2 and 0.4), a larger cup and also a quick release for the airline so was ready to use straight from the box. I’ve been using a cheap Chinese brush which has recently been having a few issues. The new brush is so much smoother in operation, no clogging so far and a very even coat applied. It strips down without the need for tools for cleaning and to change the needle and nozzle. Granted it is the entry level brush in their range but as is typical with German engineering I can’t find any faults and the workmanship is superb.
