well, I'm thinking about getting one again.. I've never airbrushed before, and I won't be using it on a regular basis - can anyone recommend a good one to get ?
For years I used an airbrush bought from a cake decorating supply. I think it was an Airmaster.
About a year ago I bought an Iwata Hi-Line. It was over $200 just for the brush. Iwata makes less costly products.
What I can tell you is this: the no frills model served it's purpose. I used it to color cakes, flowers and for detail work even though the precision was not so great. The Iwata is light years better in every application. Just airbrushing a solid color is better. The spray pattern is finer etc etc etc. You'll get what you pay for.
You will also find reasons to use the airbrush because it makes life so much easier in so many ways.
If you buy an inexpensive brush, you're gonna want to upgrade eventually.
Whatever you do, I recommend buying an extra needle right from the start. And baby your brush, they don't like being mishandled.
