Then this is a real contender:

And is about the same price as Corn Silk was before it rocketed in price and then disappeared! The packaging is a bit awkward and i prefer a fluffy powder applicator rather than a pad - but the powder is extremely translucent, very light in texture, and is nicely mattifying without being too drying.
