TRS-80 Color Computer 2 needs parts

I'm trying to repair my Color Computer 2. It has a bad keyboard. At one time there were a bunch of Color Computers in the warehouse. Are they still there? May I buy one or more if so? My Coco 2 has a 63B09E CPU, a composite adapter and a lowercase kit, so I'd like to save it if I can. Of interest to the list may be a new 68B09E Color Computer clone being created by Ed Snider. It's called "The Coco 2+" and can be seen on his website: http://www.thezipsterzone.com I'm also looking for a diagnostic cartridge for the Coco. Thanks! =[ Al ]=
