Duo Therm A/C Unit?

Has anyone considered this Duo-Therm A/C Unit? It uses the same cutout as a Fantastic Fan and therefore could be added after your build is complete and your hobby fund has been replenished. When I wire my Fantastic Fan, I will run a 110V wire so that I can add this in the future.
