My absolute favorite line for (powder) bronzers is Physicians Formula. They have so many color choices, finishes (matte or shimmer), and formulas (mineral wear if you prefer mineral formulas, organic wear that's great for sensitive skin, even a formula with SPF 20 for added sun protection).
All of their compacts come with a mirror and small brush which make them very portable. And the price just can't be beat. They're all around $10-$14 and as good if not better quality than department store brands I've tried before. They have $1 off coupons in the Sunday paper all the time, and CVS (and other drugstores) often have them on special for buy one, get the second half off. It's a great excuse to buy two! There are even a few "Try Free" offers for the Mineral Wear and Bronze Booxter formulas. Now go get glowing! - g.
