I'm 4 mths preg and have bad circulation, which means I get very cold in bad weather but VERY VERY HOT in hot weather, so this summer is going to be a nightmare for me!!! We're thinking of buying an air conditioner or air cooler for our bedroom so that I may be able to get some sort of sleep at night. Don't want to spend more than around 150-200. Can anyone recommend one? Something that is not too big and ugly too would be a bonus!
