My Thor pans were also about half of the price I got from Leader. I always talk with Arnold Raymond.
However, they now have a few more English speaking people there. I was talking with Arnold at length at the Verona Winter Maple Conf. this past Jan. and he said he is taking a long extended trip this summer. He is traveling to Alaska and was thinking about 6-10 weeks duration. He may not be available if you try to call him.
My Thor pans are every bit as good as Leader's as far as I can tell. Thor even customized them to my specs too. I had them make my flues 10" tall (raised flues) and then had them add 4" to the overall height on both the front and back pans to contain the "jumping sap". For these changes, they only added $300 to the base prices total, not each pan, on my 3x8 set. I also have a Thor hood set, a spare front pan and a draw off tank, also made to my specs, for well under what the big guys showed as their price (mine is 3 yrs. old). Arnold even delivered it From Quebec to Central NY for $50., on his way to visit his brother (now deceased) in Florida.
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
