Have you told dell you’ve been using unofficial cartridges? If so, I suggest you take the deal.
Printers are '''made''' to break down if fed any toner/ink that does not come from the manufacturer.
Since your model comes at a relatively high price, 60 $ is your best bet.
If you try to do it yourself you will need that amount minimum for spare parts+a big chunk off your free time.
It’s just not worth it.
