I have a 16" starfire nano cube in my office. Not sure who built it, but it came out of Calgary. You might want to look at my build thread (

I can tell you I enjoy the size of the 16" cube. Just big enough to leave you some room for mistakes...lol. I also really like the clarity of starfire, but I think it takes more work to clean it and I hear it scratches more easily too.
