Hello Kitty mini fridge
This may or may not be a good enough to use for the four months that the cafeteria is closed and the lone fridge on my floor will surely completely full every day. Only 15 bucks on Craigslist plus I paid another 10 to get her to bring it to my office.
EDIT TO ADD: It can also be switched to a warming mode. It'll be interesting to see if it gets cold enough (for a while) and then warm enough to bother.
