If you do buy them now, you're going to want to get an electrician out there sooner rather than later so that you don't have $1000 worth of obstacles in your shed.
Also, since we're talking about spending your money, to extend your shop space, I'd consider putting a pergola in front of the shed. You could put retractable shades on the sides and top, and even install a ceiling fan beneath it. Great place to work on projects. Plus, when it's not in use as your indoor/outdoor shop, it'd be a great outdoor space to gather around a chiminea or fire pit in the fall and winter.
