I may not have the technical knowledge, but I have the stove, so glad it helped.
If you were in Tennessee I could tell you where NOT to get one. The sweeps company I had do the install had them listed on their website store, but Buck isn't one of the brands they normally carry. After getting some estimates on other stoves, I asked the estimator if he could give us an estimate on the Buck, and he had it within a day.
I agree, there website definitely needs an overhaul, and trying to get answers through email were fruitless. I have called a couple of times now, and have gotten through to customer service, so a call to their sales dept. is probably your best bet.
I was told by another sweeps company I had come to get an estimate on chimney work that even though they don't normally carry Buck, that they could have gotten one too. So you may want to call around to local installers, but ask for a sales manager. I called this same company, but the lady that answered said they didn't install Buck stoves.
