Made as a hobby during the pandemic -- it scrapes eBay listings for laptops, and provides a parametric search (RAM, SSD etc) inspired by the likes of Digikey and Mouser, and sorts on total value. I like to buy used electronics, but this kind of search is still shockingly bad on typical marketplaces (Amazon etc)

An example search to get you started: https://www.bytebucket.co/?mincpu=800&minram=12&minssd=500#t

pretty quickly finds for example an 11th gen Intel, 16GB RAM, 512GB SSD laptop for ~$200. That sounds like a pretty good deal to me. The really good deals get swiped up within a day or two though.
