Product review (5 stars): Happily Surprised
I've had this unit for a couple of months now and I am happy to report that it has functioned without a problem.  I initially purchased an Edgestar unit which is supposed to be one of the better units.  It only lasted five (5) days before it failed and I returned it.  If you're debating between an Edgestar and this unit, buy the Great Northern unit.
