I could really use some help with my stove decision. I'm looking for an economical pellet stove for an uninsulated 650 sq ft barn (in NH) that will be used occasionally in the fall/winter seasons. I had decided on the Napoleon NPS40 but then read about a lot of problems (and had one dealer mention that they had QC problems during the gas/oil price spike back in 2008) so now I'm wavering again. The other contenders were the Leisure Line Pioneer LE (rice coal fuel) or the Harman P38. I'll throw it open to any and all advice or experiences. Thanks. One more thing - does anyone know if Napoleon stamps the manufacture date on the back or do you have to decipher it from the S/N?
