I'm looking to get one, and so far I've heard great things from Underworks, and I wanted some other folk's input. Also... I'm hoping people who've got bustier issues will say something because I'm working with d's and need something that works well and doesn't cost an absurd amount.

If it makes it easier, I wouldn't be using it everyday. But it would have to be comfortable enough to be worn during a workday where I'm constantly moving around. Any ideas??
