And i agree with that but the heater you posted is more for a larger colletion in a shed type setup, not for a small bedroom. Not many beginners will have 4-500 to toss around on a heater when they can get a oil radiator to do the same thing for a fraction of the price. I been using these for about 5 years now with no problems. And MANY others do as well which is why their highly recommended in this hobby.
