Please recommend a powder brush!

The weather is getting warmer these days, so I'm looking to buy a powder brush. Could you please give me some recommendations? Since I have combination skin (oily T-zone, dry cheeks), I only use it on small areas like my nose, eyebrows, and forehead, so I'm looking for a small brush, but it's hard to find one.

Right now, I'm trying to decide between the Real Techniques setting brush recommended by Isabae and the FilliMilli blush brush.
