Since I picked up airbrushing as a hobby and didn't really want to invest a ton of money into it, I have bought 6 different airbrushes that were cheap and everyone of them you quickly understood why they were cheap. They use cheap materials that break easily and are just copied designs of the expensive airbrushes. If you want to start airbrushing as a hobby or whatever and expect to use it more than a few times a year, just save up your money and buy from a top airbrush maker. I finally did and I couldn't believe the difference. I almost said the heck with it and gave up after sending all the cheap airbrushes back. I went out and bought an airbrush from arguablely the best brand of all airbrush makers. The quality is unbelievable and I could spray motor oil through it if I was so inclined. No clogging issues, no breakage of the trigger after 2 uses, and not having to thin paint down to water like consistency and still having it clog up. I know it sucks to spend so much money for a hobby but if you want a good airbrush that does what it's supposed to do, you're going to have to pay at least 100+ dollars on one(and that's just the airbrush without all the extras the cheaper ones come with) why else would they throw all the extras in if their products was any good? The answer is...they wouldnt!
