Sotar 20/20:
I'm finding it clogs/jams/whatevers far less often than the best of my cheap starter brushes, but I don't have any medium/higher tier brushes with which to compare it.
I've seen them as low on Amazon as maybe 60 bucks around black friday? I think 70-80 is the average there though. If you want it don't wait for the lower price as they tend to sell them out and then not get them back in for months.
You will have to thin your paints more, of course, it has a tiny nozzle tip/needle. You should be able to get a bigger needle for it too, I'm pretty sure, though that may defeat the purpose.
I'm pretty poor with mine but I could see an expert drawing some superfine lines with one. I think they're used for inking stuff sometimes.
One last precaution. Realize that these things MSRP for something like 400 dollars. Even though your brush is on sale for ~80 bucks right now, the parts aren't always subject to such a discount. You may be paying 30 bucks for a replacement nozzle tip. I had to do it once, it was a bitter pill. Still an excellent gun, I just wanted you to have all the ammunition to throw at your choice as you could have. If this is something you've scrimped for and you won't have 30 bucks in the off chance you lose one of the more expensive parts down the road, it's something to consider.
But in general...
Oh, by the way, are you talking about the Minitaire paints for the airbrush? Because yeah, you'll need to thin those. They're all different. My hazard orange and pumpkin, for instance, are ridiculously thick and will barely make it into the bottom of the paint reservoir without help

My black is pretty close to just right, though for really low PSI close-in work I still have to thin it.
If you're talking about the spectratex or similar.. those tend to run a little thinner but they're awfully glossy to be using on models.
