How to choose the most budget option of the MFP?

Question

System administration

I choose a new MFP for accountants, trying to calculate the most profitable option.
With the cost of the device itself, everything is very clear.
It’s more or less clear with toner, there is a resource of cartridges, the cost of the original, not the original, refills, although if for Kyocera this refill is always the same price, then for HP it may be necessary to replace the photoconductor or some parts, but at least something.
But with the cost of repairs it’s already a complete fog, with Kyocera ECOSYS M2035dn it’s more or less clear, 100,000 drum life, and then a repair kit and maybe another 100,000 will print, then to a landfill, and for HP LaserJet Pro MFP M426fdn nowhere to find such data.
Where to look for them?

Answer 1

Look towards the MFP from brother The
drum is separate from the cartridge, cheap repairs
