Best Make Up Brushes

[WaitMonkey]

I've decided to update my very old make up brushes, and treat myself to some new ones. Any recommendations please ? I've heard good things about Mac brushes.

Real Techniques are fantastic. I also have Sigma (quite similar to Mac) and a couple of Mac.

Second what Frankie said - the RT stippling brush is really good, but I do follow up with a buffing brush.
