@Evil Space Elves: those just happen to be my only two armies! I'm now looking at the Badger brushes as well.
And in addition to your podcast on the subject, please pin a thread in here about them. @Woozl
that's good news since it was seeing your army that was the straw that broke my camels back in terms of deciding I needed an airbrush! Do you use the 0.35mm nozzle? @Ispa
you're right that there needs to be a better beginner resource! I think my problem with airbrushes is that I false started with a hand me down all-plastic Aztek brush and a Frankensteinian air compressor that my older brother built from scratch. We actually called the thing "the bomb" because that's what it looked like!
I tried using that to paint vast swathes of gaunts, but it was pretty much perma-clogged, so I resolved that airbrushes were horrible things.
I'm now revising my opinion and looking to invest in some reliable kit, so I appreciate all of your help and opinions!
