Well I have the Megamini's Droyne and I like them, even if there isn't that much to the set, ( I think you get 3 warrior all the same pose, 1 sport and one worker caste) .You might be able to proxy them by using GW lizardmen Skinks, they're a little more like raptor style dinosaurs, but for 28 bucks at the Warstore I got 24 of them. Only problem would be to get wings and Sci fi trappings.
When I talked to Megamini's they said it was unclear if and when Marc Miller would produce the droyne, so it may be a while.
