<p style="MARGIN: 0in 0in 10pt" class="MsoNormal"><span style="FONT-SIZE: 9pt; LINE-HEIGHT: 115%; FONT-FAMILY: "Arial","sans-serif"">I am surprised that no one has brought up Iwata Airbrushes.  I have used a Paasche, a Badger, and a Iwata, and by far the Iwata's work best.  Double action are nice, but you really don't need one, especially if you plan on using paints other than Acrylics.  I used to do some pretty hard detail with my Iwata when I made 1/35 scale tanks.  I think the most important piece of equipment is a good Air Compressor.<span style="mso-spacerun: yes">   Which I see that you now have one.</span></span></p>
