Dixie Art, Coast Airbrush, or Bear Air seem to be the most popular. I got my Omni 4000 from Dixie Art and have no reservations about recommending them. I've had a 3000 for a good while, but never had a gravity feed brush so I got the 4000 last week. I think you've made a wise choice, but if you get it from Dixie make sure they have them in stock. I got the last one they had
MikeV has a good source for Badger / T&C products. They give 40% off of list to FSM users, all you have to do is mention that you heard of them from the forum. That puts them at about the same price as Dixie Art, but I don't have the phone number. Mike, Where are you bud??
