Eek. $200 is a lot for a 10x10 IMO but like you said, it all depends on the area. If there is power available at that price it would be a better deal.

Since you said you move enough material to go to the yard at least once a week I would think you could swing it. I work out of a 10x15 with no power and it pays for itself and more with me only going to the yard once a month. I use it to hold my stockpile, some personal stuff, and work in, so I figure as long as it's not costing more than it makes I'm good (for now) My storage unit only costs $150 month though and scrapping is a very part time thing for me.

I thought I would have room for a trailer too but that space filled up veeeery quickly..
