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 wasn’t able to find anything definitive online, but its specs and functionality sound pretty close to BennVenn’s Joey N64 cart reader/writer. https://bennvenn.myshopify.com/products/joeyn64-cart-flasher
