Get me a can of gasoline, no forget that, too expensive!!!!!! How about charcoal lighter fluid, a couple of sticks and a bag of marshmallows.
Now that's a party!!!!
Seriously, remember that the more destructive you are with the shed, the more little tiny obnoxious pieces there are to pick up. I like to cut in large panels that are easy to load onto a truck. When you do it crudely, you get lots of awkward parts that can be harder to remove.
If there is a concrete foundation or pad to deal with, go for the heaviest electric jackhammer you can rent, and find a few friends for that. Use the same philosophy for breaking concrete, lots of easy to manage chunks, not a pile of rubble. Too hard to clean up!
