I used one of those bulb units on a pcb out of my galaxian, I know I made a mess of it. I am still tracking my mistakes. I bought one of the Hakko's, and all I can say is WOW. I have done a number of things with it, replaced chips on my system 1 boards, put in an Nvram and replaced many components on a Pinbot PCB. I would never go back to anything else.
