I have seen some Onslaught minis before, but either I had totally forgotten about them, or in the last couple of years, they've expanded the ranges exponentially.

Previously my favourite 6mm scifi mini manufacturer was Plasmablast Games, but seeing as I have all of their miniatures (many unpainted--naturally), I need some more to hoard... er, I mean, collect to studiously paint and play with.
I think Onslaught are now my first equal favourites with Plasmablast. Check these out:
I can hear Freddy Mercury in the back of my mind subliminally telling me that I want it all and I want it now.
