There's a million different kinds. Some are good enough I don't miss
lead, though time will tell if the joints hold up. Currently trying
out the new germanium doped varieties. Anyone else tried those? And
then, of course, there's bismuth.... Collect a few different types
and you can do four complete hands-off reflow passes to assemble
boards with components on both sides! Useful for hybrid attenuator
assemblies.

Still shouldn't mix any of it though, especially not with leaded joints.
