Has anyone used the edenpure heater advertised on paul harvey?

If you are considering one of these heaters, first check out Portable Furnace, they work on the same principle but you can replace the bulbs in the Portable Furnace but not in the Eden Pure. Some friends of ours purchased two of the Eden Pure and they love them and it does cut their heat bill, (natural gas) but it does increase the electric bill, but they claim even though the electric bill is higher it is still cheaper than the natural gas would be......good luck in your search....
