I have two of the Sportman's condos and my Dad has a couple as well. His are SC1's and they are very small. Not enough room for even a single hunter, IMO, and difficult to maneuver around. I have the SC2's and they are about perfect for one hunter, but honestly wish I had gotten the bigger ones. But they are built well and very nice all you need are 4x4's to elevate it. Mine don't leak and windows are pretty good. They do get hot when it's sunny and warm. I think they are a much better value than $3500 for a fiberglass blind.
