We still have 4 or 5 around. I think most are 8' though. The moldboard poly is pretty decent, we re-inforced ours when new/when we got them so they'd last. It's not my 1st choice in a plow, but I do prefer poly compared to a steel plow.
I know a business that has one Poly and one steel plow. Although they arent used very much, the steel plow/truck is always outside and is in poor condition and the blade is basically rusted through
