Has anyone used the TestMaster? It is a handheld unit I saw at the Long Beach Show and am thinking of trying to find one. It tests all of the following systems. Let me know if anyone has used it. I know it is being Beta Tested right now. Does anyone know if there is anything else out there that tests all of this stuff.

Thanks
