Ok, I know miniatures are not required for DH, and many people happily play the game without them. So that one's out of the way.
However, many of us enjoy using minis with WFRP and DH, so I am curious to know what minis do you use in DH? Obviously 40k has loads of suitable ones, but the trouble with them is you always need to buy units, or that the individual minis are pretty darn expensive. And to be honest, there aren't that many GW figs suited for acolytes, citizens cultists etc. Imperial troops have a couple of boxes like the Witch Hunter and retinue, IG comissar's, and so on.
Necromunda minis would be pretty useful, but they're not so commonly available. Luckily I have a few stashed away. Then I see people have used various plastic GW minis to convert their own. WFB Empire Militia seems to be popular. WFB figs might have other usable types as well, I haven't checked them out too carefully these days.
Of non-GW figs I like Pig Iron militia and other troopers. They're pretty nice not-IG or maybe planetary defence forces. Then there are the rebels (cultists/hive gangers?) and the more high-techy troopers (stormtroopers?) An additional bonus is they come with separate heads, so you can always do a little headswapping. And PI figs aren't too expensive.
I also have my eye on some Infinity figs for certain assassin and fighter types, and both Copplestone Castings and Em4 minis have some great 'dark future' types in their selections.
What I really would like to see is something like Consortium telepaths: www.consortium-univers.com , too bad these are 35mm, and would tower over all my other minis.
So, what minis do you use in DH?
