It really feels hopeless right now trying to get a 4GB model. It actually came back in stock for me at adafruit and I even had one in my cart! But alas they required me to enable 2-factor which holds back tear required me to log out and log back in and it was gone.

I notice even old models are hard to get, like the zero W.

the last time there was a shortage of pi hardware (before the 4) - target in the US had these "learn hardware!" boxes on clearance for a few bucks, with a Pi Zero (not sure which one, wifi only) and a cardboard case and a daughter board. I still have a couple of unopened boxes in a cabinet.

Unfortunately, i've lost about 2 pis a year to hardware failure since 2018, usually the SD card overheats and practically melts. I'm not sure why, humidity maybe, or bad SD cards.

I've had this happen to me when the SD card would snap in 2 inside the SD card holder on the PI. Happened twice with the CanaKit PIs, once for PI3 and another time for PI4, with the SD cards that came in the CanaKit. I just put Raspbian on some fresh SD cards that I bought separately, plugged them in, and everything was back to normal. I think the overheating was from the short circuits inside the snapped SD cards.
