I've considered it a few times over the years, even pulling up webpages that show them. There is an electrical outlet on my porch that I could use. I always have at least 3 flats, though, and that jacks up the price to get started, so I've just never made the leap and actually done it yet. Assuming I land a job that keeps me here, I'll consider it one of my "splurge" gifts to myself. :)
