We built a 40x80' about 10 years ago that was cheap compared to today's prices but do I think it will pay for itself in 20 years? Nope. Would I ever give it up? Never! It's not like you can't do some of your own service work outdoors but I prefer doing it in Jan in a heated shop vs in June when I should be spraying or field scouting. It's also a fun place to hang with then farm crew after a days work.
