the manual controls are not hard to come by, several sellers on ebay offer "rebuilt ones"

Yea, but, want to get the original one rebuilt, not buy a rebuilt unit.
you would probably have to reach out to one of those sellers, cardone does rebuilds on things and probably some other places but you may end up paying a premium for that.
there is probably a couple dozen of these out in my local junkyard as we speak

Don't know if they are good or bad.

They're not that difficult to disassemble and clean. I had my AUTO one apart, cleaned the buttons and the two temperature pots, and replaced the bulbs (from www.carradiobulbs.com).

the manual ones usually just get worn over time, the "turn" knob has a copper leg that switches position inside the control to a corresponding copper leg over time they get **** built up and maybe even burnt some, this causes loss of contact and the control then may only operate sporadically. the plastic bits inside also become VERY brittle so if you open one up you have to be very careful.
the digital ones are more prone to failing electronically and the lights burn out. one thing they will do is work intermittent, it may work upon a key cycle for a few minutes or may just stop working mid-drive until you cycle the key again, this often create a headache because then you are chasing a ghost thinking the ac is low or pump not working etc...
then.... in either analog or digital on the gmt800's the blower motor resistor takes a crap and throws another troubleshooting step in the mix

ISS Automotive in Bonney Lake used to repair them. https://issautomotive.com/collections/hvac
It's almost 2 months later, but I got a rebuilt one (digital control) from "pro-rebuild" on Ebay back in October 2023:
Installed it and had no issues for a couple weeks, then had the power button stick. Messaged him and he sent a new one out the same day and I got it a couple days later. Sent the old one back, no questions asked. Highly recommend. Still no issues today.

The voice-over in the eBay video sounds exactly like the guy who does the "I do cars" YouTube videos. I'd bet it's that guy -- they're around St. Louis.
