I don’t think that off-ease laptops are very good as they are sold. The batteries are often on their way out and so that’s an additional expense (and some, like Macs, are very expensive to replace).
There are some incredible deals on off-lease desktops, though. Most modern computers are way overpowered for what the average user needs. You can get a perfectly serviceable machine for doing email, serving the web, and office work, for $100 or less. Just don’t expect to play any games released within the last five or more years.
Several years ago, we were given clothes by a woman whose husband had died. I still wear some of them, and we refer to one of the shirts as “the dead guy shirt”.
