This. If it was your sole tool for daily tasks it makes sense, once a month to edit a config file…not so much.
When I started working we had HP Unix Silicon Graphics systems, VI was our only text editor…so I have some commands as muscle memory. The rest of commands I open my tractor feed help printout from 30 years ago
Craigslist is fine if you use the email relay ( don’t use your phone number ) and pre-vet people. You can usually get a sense of who is legit. As far as coming to your house, andly stranger could they don’t need a craigslist invite. Just don’t say “today doesn’t work because I’m not home.” You can also check if there is a local hobby group on Facebook Market place.
