[GZG] Questions for the listmind

Hey all, longtime lurker, needing to ask a few questions to the Stargrunt
experts out there. I have a friend who's decided to give SG a try, which is
good, but he wants to use a TAU army from WH40k. I have no problem with that
(they are good looking minis), but I need someones help statting them for SG.
Any ideas would be helpful.

I am also looking for some Heavy Gear style 25mm battlesuits for another game,
something larger them the (very good BTW) GZG power armor, but smaller than
regular mecha. The old RAFM 1/87 scale Heavy Gears
would have been perfect, especially the larger ones, but they are out of
production and out of stock everywhere I've looked. I need several different
styles, to represent a couple of different human and alien factions, and any
suggestions as to what could use would be most appreciated.

Thanks in advance.
