What you can't do and nobody will ever do without one is a chalky looking, obviously airbrushed gradient. And that's a good thing. Of course the main thing you can't do without it is get perfect primers super fast or large flat areas of absolutely smooth coverage in seconds. Even if you spend years perfecting these things, any rando can pick up a $30 and do the same with less effort. Which is why they became ubiquitous (that and retards thinking a tool can improve skill instead of practice).
Nobody will ever become a better painter because they bought an airbrush. But they will have a whole lot more spare time to work on getting better.

MMF has hundreds of good busts. Or if you are in 2010 and don't have a resin printer you can just etsy them or get one of the 20 people at your LGS who have them to print a few for you. Artistan Guild, Witchsong and uhhhh....Archvillain I think? make typically fantasy-sci fi busts for starters. AG makes 5-6 busts from their regular figures every month now. This one is from Witchsong.
I got a couple ones of Warmachine characters that are cool if you want one.
