Aegis Figures has released a set of eight 28mm scale sci-fi "ganger" heads for conversions, and a pair of very modular 28mm Bug Warriors - insect men that would make excellent thri-kreen proxies for Dark Sun players, as well as good low-tech aliens for Pulp and sci-fi use. Some nice, useful minis, hopefully just the first of many from this new company.
And thanks to Reviewing Wargames for pointing me (somewhat indirectly) to this new, small manufacturer.
