Actually, I learned a lesson over today. That being, "you get what you pay for". I had bought a cheap dual action airbrush kit on ebay and I got to test it (sort of) today using water only. It didn't perform well as it was slightly pulsing as I sprayed. Knowing from reading some troubleshooting text that I had an air leak somewhere so I tried to tighten everything down which included the nozzle which I was attempting to hand tighten and it broke off. I was amazed at how tiny the threads were and how easy it broke which I immediately determined this airbrush is absolute trash. So I am shopping once again. I am retired and on a budget so I can't spend a lot. I have been looking at the "Master Airbrush" line and hoping to spend around $50 which I know isn't much but I have to keep the price down and since I am only starting with this new hobby, it's kind of a "try it before you buy it" situation for me. I am open to suggestions at this point so I would like some suggestions on what to shop for. Thanks in advance for any help on this.
