Unfortunately most of the PCB fab companies only print off PCBs in at least batches of 5. I bought enough parts to make two cart readers and split the costs with a friend to help drive the price down into the low hundreds.
I don’t know which number you were looking at when you saw the Sanni was “so expensive”. You can get an assembled Sanni v3 for about $150 online. https://savethehero.builders If you join their Discord, there’s also folks selling Sanni v5 DIY part kits for $110-130 depending on what add-ons you go for. https://store.starshade.dev/product/oscr-hw5-complete-kit-diy It’s still a pretty penny, but significantly less than some of the $250 pre-assembled stores online.
I think you’re dramatically overestimating how much people want to discuss politics with a stranger who slides into their mentions pointing out logical fallacies.
