Who's going to install it?
Who is going to come out to your home if you have a problem with it? (Warranty work.)

There's nobody nearby who sells fireplaces?

As far as I'm concerned. when I'm going to purchase something that could potentially burn my home down, I won't just look at prices. I want to be positive it's a unit that I can have installed by a certified professional, (my insurance company likes that too) and I can get service when I might need a part or something. I always have done business with my local stove shops.
