How about calling a few Harman dealers? Would be interesting to see the variation there for your area. Maybe a few other brands as well? I have never purchased a stove new so my need for dealer/factory service is parts purchasing, which personally I feel is the most important aspect of stove ownership.
In my travels as junk collector and stove refurb-a-holic I have had opportunity to call on three Harman dealers, that was not a nice experience, terminal hold twice and on the third didn't have the part and wouldn't order it unless I drove down there and paid first.
I was able to purchase a hopper from the nice folks at a Harman dealership up near
I have also purchased from LL factory store, didn't call just stopped by on my way back from getting coal. Had everything needed. Went to the Alaska factory store with Jpen, friendly folks there, didn't actually buy anything. Bought some stoker motors and grates from the fella out by Honesdale that is a farmer andpart time Alaska dealer, another nice guy to deal with. Have purchased numerous items from Keystoker over the phone, armed with my stove build number I have always gotten what I needed within three days of the call. Went to Country Fireplace in Dupont, they sell LL and Keystoker mostly. Bought Alsaka glass and Keystoker glass, very nice folks. Then there is purchasing numerous generic items on ebay like gasket material, gasket cement, etc........
So not only is it nice to have this forum and the wonderful people who contribute, but the manufacturers and dealers both large and small that are willing to support their products after the sale......... I SALUTE YOU.
