I have had good luck with Champion bras (from www.championcatalog.com, not the C9 brand you can get at Target), particularly the seamless models. They are comfortable, supportive and wick as well as anything else I've tried. I'm a 34A, if that makes a difference. Two or three times a year they have huge sales where all of the bras are $19.99 each -- I usually buy a few every time they have this sale.
