MAC's moisture tint and Bobbi Brown's tinted moisturizer are both great brands that I've tested out. They give very light, natural coverage and cling to your skin. However, my favorite method is still to use a small screw-top jar, fill it with about a teaspoon of a light SPF 15+ moisturizer, then add 1/4 teaspoon or less of foundation and mix it with the cleaned end of a brush.
The nice thing about making your own tinted moisturizer is that you can use up foundations you normally don't use, either because you don't really like them or the shade is a bit off. That's because the coverage is so very light that it just blends in to your skin. This is how I've been using up a Wet n' Wild foundation that I despite the oily texture of: I use the tablespoon of moisturizer with maybe 1/8 teaspoon of the foundation, and it gives super-sheer coverage while clinging to me better thanks to the moisturizer.
