I have enjoyed SG1 and owned it's first 3 seanons on DVD for a long time now. I recently started using NetFlix and I have started season 4. So this weekend I have the first three disks of season 4 to watch.
The commentary tracks on the SG1 and SGA dvds really make it worth it. I have all the seasons of both shows in the smaller package format but I think there is a new release of SG1 that has every season all in one box which takes up even less space.
I love the way SG-1 "ALMOST" gets the cool ships. The had a pyramid ship for a short time and I was kind of hoping they would get the Jack ONeil from the Asgard. But it kinda blew up before it was even finished.
