I use them, they are real good. I got mine from red hawk trading in ID. They are my favorite tent, works good in any weather. Feel free to PM or call me with any questions.

After a little research, I am looking at the 12 man from Seek Outside. These tents seem so much easier to setup/teardown than a traditional wall tent, but the durability/longevity is what scares me.
