Hello, thank you for your comments. My replies below:
1) There are third party sellers, with which I have no business association. They are listed in the wiki: https://junkerhq.net/240p/
I'd recommend asking for them to download teh latest version before shipping you a cart, since I've updated several times and don't know their process.
2) I don't own a KV-36FS210, so I can't tell you how it works. In other words, it is device dependant how each TV stores its settings. SOme do it by input, some are general.
Regarding switching consoles, you'll have a general calibration with either version. But each console has its own daeviations, so you might find there are differences. You'll need to find a balance that works for you.
3) Again, no idea. Depends on your TV.
