For things that require RoHS, I've been using a version of lead-free popular with assembly houses- Sn99.3/Cu0.7 2% flux, which seems to work okay. 

The joints are not quite as shiny as the beloved Sn63/Pb37 with RMA flux, but quite acceptable. 



Left two joints are lead-free, right joint is Sn63/Pb37. 

Lead Free Soldering and bad looking joints
I've started playing Eclipse Phase with a group of friends. Most of them have a Dungeons and Dragon history, and love getting magic items and such. I've already made up my mind to take the party on more dungeon raids, but what specifically can I do in the way of loot? It is a hard science fiction setting; no magic. It's noted in the core book that some brand-name weapons and items will have special features, and there is something called Psi that is basically watered-down psychic abilities. What are some recommendations you would make for drops and treasure caches?
