Dell Latitude 5000 series are usually bought by corporations for employees. They are made of sturdy metal, and have features like backlit keyboards and physical trackpad buttons. Then, after 2-3 years, or if they have some minor problem, they end up in a giant stack that either never gets diagnosed, or just gets sent to recycling.

I have had fantastic luck getting a couple of these either direct from the company I’m working for, or from ebay or a company that recycles laptops. They usually don’t actually have a problem, and if they do, parts are readily available on ebay. You can end up with a high-spec laptop from just a few years ago for practically nothing.
