Trying to get the wife out with me this year. We just bought a brand new ice shack and now I'm ready to outfit it with a heater. I'm looking at some space heaters, but I honestly have no idea if I need to know anything about what kind of gas is better or how big I can get. The ice shack is just a 2-person, pretty small. I've been looking at some NewAir portable heaters (anyone tried these?) but I'm open to any selections and if anyone knows of other sales, let me know.
