Cheap printer[ say £100 or so]
Expensive replacement carts[£30/35 each= 120/150 a set.
So pick a printer you fancy then price up replacement carts,and imaging drum and waste tank.
You could look at refiling as I indeed have.
But as the Carts are chipped these days- you have to consider getting around that one.
It can be done - if you are into getting to the mother board and soldering on a chip to a processor chip that is this size ...
needs four leads out of the six lands.
and two more at a similar spot.
