The micro servos are no drop. So the combiner needs to get some of those.
But the wire and staff are tradable.
One quest you might want to look into is Gleeds Bow. You can do this quest at level 5 basically (or, whenever you get sneak)....
Mostly because all it takes is a high level taking down vluudeen in great divide (and tons of high levels are always passing by there). Then you take the tail to the giants and sneak turn it in (getting to Gleed to sneak can be tricky though)
But otherwise the bow is really really nice. A 20/30 with 180 range.... and at level 49 it starts to proc an 81 damage DD
