There are plenty of devices that are cheap AND repairable - looking at a ~15-year old Brother HL-2140 printer by my right hand that still has all key parts readily available (not that I ever needed to change anything other than drum and toner, but parts are there)
The secret to cheap repairability is actually quite simple - make a good, no-fuss model and sell it for long. This will remove the necessity to print specific parts in small batches for older models, and by the time the model actually gets retired, there’s so much spare parts you barely need to produce anything at all.
Granted, this doesn’t work that well with ever-evolving stuff like computers (although it does to a certain extent), but most other tech is just fine a decade or more in.
