Does anyone know of an electric water heater that will qualify for the federal tax credit?

I need to buy a new water heater and it has to be electric. The way I am reading the requirements to be eligible for a tax credit, the electric water heater has to have an Energy Factor of 2.0 or greater. I'm not finding any electric water heaters with an Energy Factor above 0.98 though. Any specific brands and model numbers of a qualifying electric water heater will be greatly appreciated.
