Sam's used to sell them here. They had one about "whole house" size for
$350. That was a little over 10 years ago, so no idea if they stil have
them, or what they cost if they do. It is way too humid here for them to
work except for a handful of days a year, but I guess they are better
than nothing. The main thing is not to try to use one as an air
conditioner with all the windows and doors shut, so that the air inside
just keeps getting more and more humid until it is practically raining
inside. FWIW, in west Tx, where they are more common, they are called
"air conditioners", as opposed to "refrigerated air conditioners"
