BTW: I found this unit at Lowe's for $319. I also looked at Home Depot and two other local appliance stores as well as two pawn shops and craig's list. All of the other units I found were to large and/or required regular draining. This is a 5000 BTU unit designed to cool 250 ft^2. It seems that they jump to 10,000 BTU and 400ft^2 as the next level up.
