My pick would also be the Dayton Electric heater. Propane is sky high in price, natural gas is about the same, and a fuel oil/diesel torpedo isn't much better and a bit hard on fuel. In east Texas with the weather being in the 40-50° F range, the electric will knock the chill out of the air just fine. You will see that the comfortable working temperature will be in the 60-65°F range.
