Hi Kane,
What Badger have you used?
Like Patrick, I've used a lot. I currently own Badger, Iwata, Sparmax and Paasche.
If i were you, i'd go for a Badger - for an all-rounder, look at at the 100LG.
The 100 and 150 series give you the option of changing needle and head sizes (fine, medium, heavy) so you can do anything from fine detail to large base coats.
I found i could get very decent fine detail with the Fine head, and it's probably the one i used the most, until i upgraded to the Renegade Krome (also by Badger).
However, (and this is my experience only) avoid Vallejo like the plague. I bought a heap of their model air range as people were touting them as the next best thing since sliced bread (mainly European modellers) - but i had nothing but trouble.
Despite them being "already thinned for airbrush", i was still thinning them down by a further 30% - 50% to get them to flow. Then they suffered from dry tip and then they end up clogging in the nozzle anyhow.
Further, they react poorly to most other acrylic style thinners (like Iso Alcohol; Windex etc) so you need to buy their proprietary thinner.
They severely clogged my medium nozzle of the Badger 100LG and i ended up dumping them all. I'd never risk putting them through any of my airbrushes again.
Anyhow, my experience only, others love them and never have a drama.
Hope my suggestions help regarding airbrush selection.
