I don't have experience with them, so can't make direct recommendations, but friends seem quite fond of Orca suits. I see a number of offerings from them with both pockets and built-in bras. The brand as a whole seems to get pretty good reviews (from when I was reading on them), and they're on the not-too-expensive side.

I'm in awe that you find built-in bras effective, with big boobs! They create one, big, bouncy, uncomfortable uniboob for me, and I far prefer my separate sports bras (which manage to separate, encapsulate, and support, in addition to offering some compression). Thus my lack of an ability to give you any proper reviews or first hand experience with suits with built-in bras. :-)
