Our local Target store is closing them out this week at $20. If I didn't already have two, I would jump right on that. More seriously, having an extra burner and pot around comes in handy if you are doing all grain. Use one for hot liquor tank and the other for a direct heat mash tun or for starting the boil on first runnings while finishing the sparge on the rest. You can even use this for a double batch day or for a friend to brew his own batch while you are doing yours. Having a spare is also handy in case something malfunctions on the other one.
