guys, I decided to get an airbrush and was wondering what you all recommend for these tanks. I want something that is versatile and easy to use. I really don't know much about them as far as size of needles I would need and single or benefits of options like a single or double action brush.I know alot of you guys are using them and I want to buy something that is going to work right and last a while...I would like to get something relatively inexpensive if possible. Thanks guys.</p>
