I was wondering if anybody has bought a steel building kit, and how happy/disappointed they are with it. I have sent off to a few makers to get catalogues and pricing info. The building size I'm interested in is about 24'wide 30'-35'long and 12'-14' high. Is there anything I should know about before deciding to buy? I don't plan on buying just yet, but by this time next year I will be, just doing some research before I do.
