I've long been an advocate of mining the planet Mercury (if one can get around the obvious difficulties of such an extreme environment on the surface). Early in the planet's history some unknown cataclysm (possibly similar to that which resulted in the formation of our own moon) blasted off most of the rocky outer crust, leaving the core intact, which means its easier to reach than those of the other rocky planets. The amount of palladium there (not to mention all the other goodies) should tide us over for the foreseeable future.
