http://www.one2fit.com/en_2_cat79_sub123_product2363.htm this is an electric heater I am thinking of purchasing. Currently I have propane and it runs me 400/month on the budget payment plan. This is with plastic over all the windows etc. This unit averages $1.00 to $1.50/day and heats up to 1000 sq foot. So they say.......... Looking for opinions and experiences. If it is as good as it says, then the $450 price tag would about pay for itself in the first two or three months of hard winter. Does anyone use anything that is better maybe?
