Anyone use Versatube? Would like opinions for garage build.

I seriously contemplated one of these steel frame buildings before I built my pole barn. What I found was they were extremely reasonable via various "carport" style construction companies, until you strayed from the basics. If you are ok with with standard shape, roll up doors, 3 or 4 /12 pitch roof, then I think you can save some real coin, especially with lumber prices today, vs traditional construction. Good luck!
