Aztec A470. Had it for years, it sprays everything from very fine lines to wide coverage. & you can swap between 4 or 5 cups depending on how much you have to spray.
Yes, the insides are plastic (although I think the latest one is all metal), but the only way to break the plastic is to force the trigger when it's very obvious that it's stuck. After doing that once and sending it back under warranty I learnt how to pull it apart. Voids the warranty but means you can clean it fully on the very rare occasions when the trigger does gum up. (hasn;t happened to me in 7 or 8 years)
There's a couple of tricks to keeping the nozzles clean but everything is very simple and it's 30 seconds after each spray session.
I actually got a sonic cleaner on ebay for $20 some time ago. Chuck the airbrush in every 2 or 3 models and have not had any problems with it since.
People ether love or hate Aztecs. I've tried other people's Badgers and Iwata's (I've also got a knockoff of one of them which I don;t use) but they can;t do anything the Aztec can;t and are far more fiddly.
I think it's what you're used to. Aztec was the first brush I used and I doubt i'll ever change. If you learn on a long needle, metal brush where you need 2 or 3 different types then that's what you'll stick to.
Each to their own
