I think 2002 was the last year for the wall mount. An issue with wall mounts is the lost of the cabinet space. Ceiling mount I believe does a better job cooling.

Yep for the wall units, I think you can buy a window unit for replacement, but there will be some sheet metal work unless you get the same dimension unit. There was an owner who wrote up about replacing his unit with an off-the-shelf window ac unit and my memory was his only issue was sheet metal.
