Airbrush problem!

I'm one of those big fans of Aztek airbrushes.  I own two, the A320 and the A470.  The A320 is a GREAT single action airbrush.  It uses all of the nozzles and cups that the A470 uses.  Therefore, you can spray fine line to broad coverage and gravity or siphon feed.  It's internal mix and very easy to adjust the spray.  Here's a link: http://www.testors.com/catalog_item.asp?itemNbr=44

Bgrigg is right ive got a 100lg and a 175  both are great brushes and under the $100 doller range at dixieart.

I'm not familiar with the Aztec line, except some people despise them and some love them. I recommend the Badger 100LG dual action available for $64.95 at Dixie Art. There are others who will recommend Paasche and Iwata, all of which have models (and all of which are available from Dixie Art) well under the $100 limit. A good deal is the Badger 150 Pro Set which includes Fine, Medium and Large needles & tips, color cup, 3/4 oz jar w/adapter, 2 oz jar & a 6' braided hose for only $74.95. This is the same AB as the 100LG except it's a siphon fed brush. I own both. The big difference between them is that the 100LG can spray slightly finer lines due to the simple fact that it can spray using less pressure. The tips & needles (in fact all parts) are interchangeable between the 100/150 line. Only the main body are different, and that only because of the different methods of holding the paint.

It sounds as though the airbrush body is kaput, and Testor's does NOT cover them with the lifetime warranty.  If you want a great single action airbrush for under $100, get a Paasche H.  You can buy the H Set which includes 3 tips color cup, large and small bottles, and a braided hose for about $49.95 from http://www.dixieart.com/HSet.html Its a great brush, easy to use, and reliable as an anvil.
