I bought two recently on ebay, a brand new m1 8/256 for $340, and a virtually new late 2018 8/256 for $265. Both have the latest Mac os. And both are truly fast. Just using them for basic stuff, ms office, surfing, email, etc, one for my wife and the other for me. We are loaded with other laptops, desktops and tablets, but I really like the mini form factor. I'd been using the late 2010 mini for years without a hitch.
