I just got burned on an "open-box" blower purchase on ebay (it was used, abused and doesn't work!). So now I am looking at new options and they're crazy expensive. $275 is a lot for two speed fan without a thermostat. Are there cheaper options out there? Is there some generic fan that I can use here? I'm guessing the holes for the flange mount just need to line up..? BTW, stove is a dutchwest 2462.
