Your experience with Stephenson's mirrors that of others I have known and it is why I never bought one of their products. They always impressed me as lots of ego and superb marketing, but, very little REAL mountain experience.
The MEC-ID "Hammerhead" tent is one I AM familiar with and was the most hideously coloured and utterly superb mountain tent I have seen. I would LOVE to own one and am POed at myself that I did not buy one, when I could have.....hindsight, ya know!
If, this is in good shape, ESPECIALLY the FLOOR, I would look no further and just buy it. Evan is a rather grumpy guy, but, his designs and build quality are among the VERY finest and I have LOTS of his gear and have NEVER had a flaw in any of it....the ONLY maker I can say that about, except Hilleberg.
I am a picky old phart, but, I will gladly pay for real quality and ID is that, no bs.
