I noticed in today's (Sunday) Target store ad that they have ceramic heaters on sale, 2 for the price of 1...$29.99
I don't know a thing about 'em or if they are quiet, but if you have a Target store in your area it might be worth checking out *today* because the ad says quantities are limited.
Store ads are designed to cater to the region so I wonder if your Target ads are the same as ours.
Good luck and let us know what you do end up buying and if you like it.
