My favourite brush for mineral makeup application is EDM Long handled kabuki brush. I just adore it! It is supersuper soft. It stays in shape while applying, so you can really buff foundation into your skin. So it's dence enough, but still feels silky in your skin. Also the price is perfect. This quality for such a low price, I can't believe it! And not even one hair had shed from my EDM kabukis and that is almost a miracle too. I can't say enough good thing about these brushes, but... Definitely worth trying for!
June, you asked about NARS kabukis. I have two of them: Kabuki artisan botan brush and Yachiyo kabuki brush. The last one is not a classic kabuki, it has a very lond handle. All in all NARS brushes are OK, but I expect more from that expensive makeup brushes. I do not see that the price is in right balance with the quality you get. So I can't recommend NARS kabukis. You can get better ones for less money.
MAC's 182 is also a quite good brush. It is also supersoft and easy to use. But it isn't my favourite one, it isn't as perfect as my favourite kabuki. It may be, if the price would be more reasonable. MAC 182 has also another minus: if you have small face, it is probably too large for some things (for example applying blush/face pigments to your face etc.) So in my opinion it isn't as versatile as EDM's version. But still I love 182 brush too.
