Metcal is great. You hit the switch and 10 seconds later you're ready
to go. And nothing even comes close when trying to solder/desolder a
35-amp bridge rectifier from a circuit board with 1/2" wide traces. The
Metcal didn't even slow down for that---it just poured on the heat like
there was nothing to it. I've NEVER been able to do that with a regular
iron. The whole key is that the regulation is in the tip itself.

DigiKey sells some tips and the Metcals themselves, but eBay is the
place to get started if you're not made out of money.
