For anyone who’s interested, Badger Games have a webstore up and running now.
The Drantakhs are under “Regiment Games”. I don’t think they have the whole range up yet, but I could be wrong. I seem to recall there having been more heavily armoured troopers as well.
They’re somewhat costly, especially accounting for their international shipping rates, but I’ll probably take the hit once I’ve recovered from the usual November-December shopping spree.
