Energy conservation and gadgetphilia are tough to combine, but this Power Cost Controller power strip might be just the ticket for those looking to monitor -- and potentially cut back on -- their power usage. The strip's display counts kilowatt-hour power usage and tracks by hour, week, month, and year. It also monitors line quality with voltage, line frequency, and power factor readings. We're just not sure if we really want to know how much power we're using, but if you're ready for the bad news, the strip is $99 and available now.
