I've got a 8GB but I honestly don't remember how much I paid for it. I would've sworn it was less than that. So maybe $75 is reasonable.

Maybe I'm unoriginal but I've struggled to find a satisfying use for it. But I also have WAY too many computers. Home server, NAS, workstations, NUC for HTPC. The best I've been able to come up with it not better suited for one of those is an Octopi server for my 3d printer.

I'm a huge fan of ESP32 though. Those little things are cheap as hell and so small you can put them anywhere.
