I have mostly normal to dry with t-zone oily skin and I tried the some of the Bare Minerals. I thought it was pretty nice, the feel was great and it looked very natural but maybe I didn't have the right ones (or the right brushes) because I didn't get enough coverage, (I have a couple scars and "problem areas"). Every time I see that infomercial I want to get all their products, though.

For about the last two years I have been using the Physicians Formula "Mineral" powder. You can get it at any drug store. I decided to try it because I had a good experience with the bare minerals and thought it would be a cheaper alternative, and easier to find. If you use a brush it has pretty good coverage, and you can dust it over foundation. If you use a dry sponge it's super coverage, and you might not even need foundation. It's like a "thick" powder. It reminded me of Sebastian make-up powders, (which I used to love,) but it doesn't feel "gluey" or get all greasy looking and settle into lines after a couple of hours like the Sebastian.

I agree. Bare Escentials does not work well for those with oily skin. That has been my experience with it- it did not cover well and did not stay on for very long. At this point I haven't tried any other mineral foundations/powders so it may be that other brands work better with oily skin. I recently found a mineral makeup company online called Larenim. they claim their products conatain "no bismuth oxychloride which is responsible for the greasy, big pored look and the rashes that dissuade many people from continuing using other mineral makeups." so perhaps there is hope for covering oily skin! The other bonus is that Larenim offers a goth mineral foundation in white, which I've never seen anywhere else.
