I typically paid 150 to 250 Canadian. They last 2 to 3 years and meet my needs right up to the next purchase. I am due this year for a switch.
As for PCs and Laptops. All are old BF buys or rescued "garbage". I am setting up a Dell Latitude E5420 (2013) for a current need. (Official disposed by my employer and intercepted before sent to electronic recycling.) Other resurrected acquisitions that are operational are from 2013 and 2015. I can do this because "what I do have are a very particular set of skills, skills I have acquired over a very long career".
I like keeping this systems out of the garbage for a few more years.
