I found this while reading Gateworld
They have a link to a web site that shows 75 pictures of the Stargate Atlantis Series 1 and Stargate SG-1 Series 3 figures.
Here is the Link
Also Gateworld is reporting that there was a problem with the pieces of the gate sent with Samantha Carter. That story can be found here
Snippit of the story about the Carter Piece...
Apparently, there has been some problem with the Stargate and ramp pieces previously released.
Diamond Select's Web site has info on a replacement offer for those who received the wrong piece
of the gate with the Series 2 Samantha Carter figure.
I went to DS's web site and found nothing about it. What I discovered with the Carter pieces is that the pegs to support the Stargate on the stand are too big for the holes. I just took a drill and made the holes a little bit bigger and it worked just fine for me. I believe I used an 1/8th size drill bit and I just twisted it by hand a couple times.
