Before you become too concerned about stove manufacturers, I'd advocate finding a good
dealer. Your relationship with a dealer will be far more valuable in the event a stove does not perform as expected or something needs to be made right. Find one who has been around for a while, who listens to your requirements and is interested in addressing them, and basically wants your business. Research the Better Business Bureau - I think their website makes that easy. Then, and only then, negotiate your best deal.
A good dealer won't be selling a bad stove - he wouldn't want the problems. This fact alone addresses your concern.
If a dealer starts by demanding money up front, or disregards your concerns, or basically gives you the creeps, don't walk away - run

There are plenty of reputable dealers who want your business and will act appropriately. I ran away from one who was arrogant and basically read me a list of all the things they would
not do. So I added to their list by saying they would not be selling me a stove, either.
Do not shop on price alone. I like to save money as much as anyone but don't go to a dealer with a shaky (or no) reputation to save a few bucks. You are almost certain to need some help in the future, even for something simple like cleaning, so you'll have to rely upon a dealer's assistance.
I wanted a really big, powerful, but good-looking stove which basically forced a decision between Harman and Quadra-Fire. Unfortunately they're both owned by HNI corporation, which was utterly incompetent in addressing a defect that I didn't discover for months after installation. Ultimately it took the threat of a lawsuit to make them relent. I did this with the help of my state Attorney General's Office (Blumenthal, an otherwise worthless creep) but my dealer helped as well.
