Well, SG-1 stuff is on my list of things to do. Will probably be a while before I get around to it, though. And don't use the gate in free stuff if you want to see the whole thing in your renders. It's incomplete. There's a really great one somewhere else, but I can't remember where off the top of my head. E-mail me if you can't find it, and I'll search for the URL for you.
