Many of the people at mothering think as you do and won't use a microwave at all. They discuss the safe cookware thing there all the time, and never come to any great conclusions because there are flaws with almost all of them:
stainless: nickel, but less so if it's the heavy kind that a magnet will stick to
aluminum: well, aluminum
cast iron: heavy, can be difficult to clean, hard to cook eggs in until you get them seasoned really well, can't be put in the dishwasher
enamelware: the good kinds with thick enough enamel are VERY expensive
visionware: has a tendency to explode without warning. I thought this was the cookware I wanted until I read story after story of it exploding. Now, I'm not sure about whether the old borosilicate kind did or if it's just the newer stuff, but I think that's why the old was taken off the market? I could be completely mistaken about that.

I personally want the le creuset (I think that's how it's spelled?), but cannot afford it and amalgam removal too <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />.
