I'm always buying models :)
Me too. I'm not remotely artistic, but I have some moderate technical skills, so I can easily assemble, customize and manipulate to suit my needs. It takes me a bloody long time to make anything remotely decent from scratch though.
What other models to people around here need?
Some good scifi-fi environments would be great. Spaceship interiors, physics labs, military bases, that sort of thing. If not complete environments, then prefabricated parts which could be used to build them. There's tons of medieval fantasy and modern industrial stuff like this, but virtually nothing for scifi, and let's face it, scifi is a valid setting for RTS's, FPS's, RPG's, adventures, survival horror's, all kinds of games.
