Best translucent powder that stays matte?

[JLbaby]

I'm currently using the Pixi flawless finishing powder which I love, but it's £18! So I'm looking for something a little cheaper that does the same job. I've tried Rimmel stay matte after reading rave reviews but it doesn't last very long on my oily t zone.

Can anyone recommend one that lasts all/most of the day and isn't too expensive?

Thanks!

Boots No 7? They often have money off vouchers and deals.

Soap and Glory Kick Ass powder is great, it's still £12 though but it's much better than anything else 'high street' I've ever found.

Coty Airspun is a classic. Bourjois Healthy Balance is REALLY nice, but get a shade lighter than you think as it oxidises.
