Can I ask what you mean by "you'll run circles" around me regarding accounting questions? I never suggested you were stupid and would never do that to anyone, and I assure you I have my Masters too. However, I don't consider myself a "Geek". Throughout my life, I have learned as much as I can, not limiting myself to one area of expertise.
Regardless, the only places you will be able to locate a used one is from a salvage yard unless you come across one on another site. If you do find one, make sure the part number is the same as yours. As far as a new one, it is not an aftermarket part. Therefore, no parts store will sell them. I have checked the internet and came up with several places that sell them.
I wish I had a better answer for you, but those are the facts. As far as the PCM / ECM issue, I just wanted to make sure the dealership was sure of what they were asking for. A PCM isn't a cheap part.
To define the PCM, it is the brain of the engine control system. When it isn't working properly, then the engine or anything the microprocessor controls may not be working properly. For example, such items include, and are not limited to, the transmission, charging system, various emission control items, and onboard control modules can malfunction.
I hope this helps.
