Russo, I live on LI myself and just purchased a harmon mark2 last week in Pa. I was a former woodburner. While i was there the guy in the stove shop sent me up the road to get some coal I paid $6 a bag and bought 10.
A guy I work with turned me on to coal and he goes to Pa and goes straight to the breakers for his coal. Last august he paid $75 a ton for stove coal. So it is definitely worth the trip to Pa. I will never by coal here in NY there all crooks! Oh and as far as the harmon, its cranking as I speak at 400 degrees with a mix of stove and nut coal and i just turned it down for the night,enjoy!
