New shop maybe?

Hello all,

Being out of town for work during the week I find that I only have time to work on my cars during the weekend if the weather allows it. This got me thinking that a garage wouldn't be such a bad idea, I've been working out of harbor freight car tents. Having never had a garage I started looking into the pre-fab metal buildings. They've got a long list of pros. I haven't seen many cons. Anyone had any experience with these, also who is the recommended company to purchase one through?. I'm located in North Carolina, looking for a building maybe 24x26x9. It'll be on a 4-6in concrete slab.

Thanks.
