Good but cheap (!) makeup brushes?

[BitchyInnerMonologue]

I'm looking for good quality brushes, but that aren't terribly expensive.

I'd need a foundation, blusher & bronzer (I think that's what it is - bigger than a bronzer to sweep over the whole face) brush. I don't wear eyeshadow so can live with what I have just now unless it's part of a set.

Any ideas? Maybe up to £20 a brush?

Real Techniques are great, in Boots or on Amazon .

I recommend Zoeva brushes. 8 good quality brushes for £65 include an excellent foundation brush, blusher and face brush. The foundation brush is the best one I've ever used, better than the Real techniques buffer brush and the Sigma F80 (IMO).
Zoeva Rose Golden Luxury brush set

Sigma brushes are excellent and within your budget. I love their F80 kabuki brush for foundation and I've also got the F84 for cream blusher. You can buy them online from Beauty Bay

Another vote for zoeva, they're more like 10 a brush on average and less if you get a set. I love their big buffing brush for most liquid foundations, there's an angled blush brush for powder or the stippling brush is great for cream blusher.

Try the TK Maxx beauty section for branded brushes at better prices - sometimes get a bargain in there
