Just decided to pull the trigger on a Big Buddy heater from CostCo. One of the better prices at 119. I am not sure if it is the latest generation, but I do need to get some additional heat in the garage during the winter when I decide to work on the lathe. This hardware will work as a short term emergency heat source. It has the standard built in carbon monoxide sensor, so while it's safe - I would never leave the area or sleep with the h/w running.
I already have a few packages of the smaller tanks for Big Buddy Heater, now to find some quality adapters / fuel filter for the 30 gal tank(s) I keep outside for my BBQ.
