Fireishot,my dad looked into getting one or two when we lost a old outbuilding but we decided not to.He ended up getting a A frame carport that is around 20x40 for quite a bit less then 2 containers.They came and installed it on a existing slab in a day and later on we sheathed it and added 2 garage doors.I was skeptical about how it'd hold up but it has been through 2 hurricanes (it was just a open carport for Irene)and many nor'easter storms since.
Here is the website for the place
http://tntcarports.com/index.html They have tons of options but for us the basic car port and enclosing it ourselves was the best bang for the buck.Since you're shopping cant hurt to have a look.
