I would stick with a 2 - 2.5 cu ft firebox stove. Log cabins aren't known to be the most efficient homes in terms of insulation. Your average temps are milder than in the northeast, but you still get the occasional frigid dip. A Woodstock Fireview, a Pacific Energy T5 or Super 27 would work well while also giving you long burn times. A Blaze King Princess or Chinook 30 would also work. But, really, ANY 2 - 2.5 cu ft firebox stove will meet your needs. A cat stove will give you more heat output control. But a non-cat stove would work just fine.
