Everyone has their opinion on what ever airbrush they use. The ones you mentioned, who knows. If I tell you one is better over the other that's my opinion, but on the other hand you purchase the one I picked or someone else picked, and you don't like it....well who do you blame? I have an inexpensive one, I think I paid around $45 or 50 dollars for it and it suits my needs just fine. The first one you called attention to is around $120 retail, and the other, around $170 retail, what's the difference? Looks like $50 to me. Just my .02.
