I need to replace my 25 year old Vigilant wood stove and am not sure what to look for. I use my stove to heat 2000 sq.ft. and prefer a top loader like I have now. Price is a huge factor in what I will buy. Are the Home Depot stoves as good as, lets say, the Vermont Castings? What about other brands? I have heard the catalytic is better. Is that true? Please help...
