Propane prices were very high about 10 years back.I was pi$$ed about the price back then and it encouraged me to invest in a wood pellet stove.I have never look back since.IMHO it was a GREAT choice and feel I have saved a lot of $$ verses burning propane.I see some states now are charging $4.00 per gallon for propane.I now use 1 tank(500 gal) a year and filled this past august for $1.25 gal.
