If you're handy, you can watch Craigslist for free or very cheap sheds. In fact our neighbor just gave away theirs. They would have to pay to have it removed, so they gave it away. Some young men in a pick-up disassembled and took it away in a few trips. (At the time I was kicking myself thinking, "Why didn't I know about this?!" LOL)
Of course, DH is not handy with tools. If it's not a computer, he can't fix it. I must pay our handyman to repair the big stuff and I attempt the small repairs myself.
