I have a double burner propane heater I've been using to heat the
garage/shop for quite some time. I've grown tired of the smell. Does anyone
have other recommendations? A wood stove isn't an option since vehicles are
in there at night. The other restriction is that I only have 120 volts. Of
course the ultimate answer would be to have a dedicated shop, but...

I really like the $100 kerosene heater I bought at Northern last year.

which is $40 less than the BORGs.
