I have a 80,000 btu propane convection heater for sale, this heater lists for $130 (see website below), and I will sell for $65. I just fired the heater up this morning, and it works perfect. This heater would heat a 3-stall uninsulated garage if the temps were above zero degrees. I used this heater in the past to thaw my boat out in the winter when fishing rivers, however my new boat does not fit in my garage anymore, so I don't use this heater. Could be used for garage, fishhouse, etc.. Pick up only in St. Cloud, MN, Brainerd, MN or Mille Lacs lake area. email at josh_clymer2003@yahoo.com
