And another thing... cotton
wood isn't. If you are getting a burn time like that my experience will tell you the stove IS doing VERY well. Of course that depends on where you live and what outdoor temps you are competing with.
My advice... take it and smile. Your scenario isn't so bad. Save your money up and put thought into what you want to do. C/S/S EXTRA wood so you have very good wood for your new stove. Find better wood. ANYTHING is better than cotton
wood. Crumpled up newspapers aren't better, but they're as good. And if you really are stuck with cotton
wood then always step up to the next bigger firebox size, whatever brand you shop for.
I think the first good step you made was looking around HEARTH.COM. Lots of good experience and advice here, drunk or sober
. Spend some time here and think things out. Shop your dealers. Customer service is as important as the brand you shop for. You'll be happier with your decision if you take your time.
