Too late, I already bought it, Richard said first come first served.
JK I have already sold all my Keystokers before I even got to refurb them, so be aware the only reason that thing is still there is the color.
But seriously, that stove is a good deal, don't fiddle around too long, if you want it buy it. You can always run the pipe down next to the stove, would be a much better option than butchering the very efficient double pass design of that unit.
BTW, that is only 4 years old, the last year they made the angled grate, should make you a good unit with a little work and a coat of black paint to cover that awful blue.
