Bare Escentuals bareMinerals SPF 15 Foundation ($25) was the mineral foundation I ever used. While a friend back in college raved and raved about it, my experience with it was hooooorrible!
Instead of the “creamy, delicately soft texture” it claims to provide, it dried out my skin, accentuated dry patches and left my face feeling itchy and irritated. It also did not cover well and was very shimmery.
On the bright side, the wide color range, SPF 15 and the fact that you can mix and match different shades to get your perfect match are definitely its pluses. I would highly recommend you try this out at the store before you buy it.
