Actually, the rate at which a black hole evaporates (under Hawking's theory) is related to its mass. The larger the black hole, the slower it evaporates. More accurately, it's related to the surface area of the event horizon (proportional to mass squared or possibly cubed, I don't have the formula in front of me).

Also, there are theories that allow for the creation of black holes by mechanisms other than stellar collapse. These other mechanisms could produce black holes of quite small mass which would have very short lifetimes relative to the age of the universe.
