I have one that I purchased at Target on clearance for $69.00 I think the price was some sort of mistake but I did not ask a lot of questions. I have had the unit for 4 seasons now works great.
They are sold under different names at different prices but all appear to be the same unit.
You can keep it outside however it only makes ice, it does not chill the ice once it has been made. When it's hot out I keep the ice maker indoors where there is A/C. Otherwise the ice maker works harder and the ice melts faster.
