No, I haven't tried the Bare Minerals line, but that informercial tries to sucker me in every time, too! It looks like it would work really well. I am currently using another all-natural brand by Shaklee, I think it's called Minerelle. It's pretty expensive, so I only have the foundation and mascara right now, and I'm pretty happy with them so far. I don't wear makeup all that often, usually only if I am getting dressed up to go out somewhere, otherwise I just bare-face it (except for a little lip color, of course!)
Oh, yeah, I use the face washes and facial lotions in the Minerelle line, too and love it!

I'd say go for it, it really seems to be good stuff, plus you could probably send it back if you're not happy...
