Hi, there is a thread somewhere that tells you where to get the different parts needed to build your own M@g85. I'll try to find it for you and if I do, I'll post the link here.

haven't found it yet, but let me tell you about my M@g85 set up:
-batteries: 3x Li-ion (protected) AW cells those
-In case you use a 3D as a host you'll need a pvc water hose to prevent the side to side rattle of the batteries.
-A Kiu socket, or
-An AW
Mag C or D Incan Driver - Soft Start & Multi-Brightness would be really nice (you won't need to buy a Kiu socket since this driver has one in it). I like this feature of my M@g85 most. (AW sells them)
-
Dual Function Removable Cam Reflector for M*g "C" & "D" e.g. FiveMega sells them.
-a boro lens (the standard plastic lens will melt)
-reduce the tailcap resitance (subject is in the link below)
-of course a 1185 Welch Allyn bulb. Don't know who sells them at the moment.
-In case you want to use Li-Ion cells, you'll have to buy a smart charger (AW sells them)
this thread is also helpfull (read the links in it too):
