I love building them, I just hate painting them. Got my army set up so I can spam at least 90 boys in even the smallest of battles. All of them either gray or just foundation black but hey, you should see my Looted Wagons. I made a wheeled Git-Burna / Looted Wagon comination out of a Land Speeder and a couple of Buggy parts.
A lot of the people got into w40k through the games, sure would be nice to have a few miniatures at my desk as a fan, but otherwise to expensive really, for now.
