I have some free 3d, untextured, lo-res props
Go'auld Staff, Zat, rings, Stargate (minus the letters, keep meaning to go back and redo them), Death glider, Drd (dtd? I keep mixing the anagram with Farscape..;)-the controls for the gate, started the P-90, but found out it's actually a real gun (HK), and it's still a bit over me head..;)
They're probably good for medium or distance rendering; as for the uniforms, they're pretty much standard, I remember someone's actually working on go'auld armour, and a while back someone had a thread for staff weapons and zats, so someone did some really good models in Lightwave (alas, out of my price range..;)
Do a search in the forum for 'stargate', the actual postings are probably 6 months or farther back. IM me if you want the models, I'll scare 'em up as early as tonight if you'd like.

I wish I'd said that.. The Staircase Wit
