Glad you like, 6mm is passion of mine, partially for space reasons but also because it allows a larger scale of game. Personally I don't get too hung up on the painting, most of the time you don't view them any closer than arms length anyways, i'm happy as long as I get a good visual effect with a mass of troops from about two foot away.
As for the tripods, as far as I'm aware they are unavailable. They were made by a gentleman over on the Tactical Command forum and the very spindly nature of the legs meant that they were pretty difficult to cast. Can't say too much as they were based on a copyright design.
