Selling this Haier window A/C: http://www.target.com/p/haier-5-000-btu-mechanical-window-air-conditioner/-/A-12212394

I used it last spring in a pretty large (and hellishly hot) room and it did the job pretty well. It's loud so I usually kept it on during the day and just used a fan at night.

$60. There are some minor dents in the back that don't affect functionality. Window brackets are installed, although you'll probably need some screws if you want to mount it.

Email me if you'd like some pictures, or have any questions at all. I'd be happy to let you come by to take a look at it.
