Radio Shack did sell them years ago. If you want one even more powerful that just costs a couple bucks and you can get it today, go to Wal-Mart and in the cosmetics section they have one that is a magnifying mirror, about 6 - 10X and it will really light stuff up! The fact that it is magnified makes it much better for these uses but the fact that it is apparently glass would make it more fragile than highly polished stainless steel. My brother polishes the bottoms of soda can alcohol stoves so they can be used for this as well.
