I've been looking at this. I'm just kinda getting into it as well. I modded my Poker 2 with a cheap radioshack pencil, but it kinda seemed harder than it needed to be. The tip was too large and I found that you really need a holder for an iron.
I just don't like the chisel tip that comes with that Weller. Is there a small conical tip I can get for cheap with it?
