Warranty is important- I've had replacement printers supplied from the manufacturer due to the availability of a warranty and, in business, you don't shortcut areas such as warranty. This issue isn't as crucial as it once was in the heyday of paying $2000.00 for a printer. In today's computer world, a top printer in inkjet or laser versions. is now very affordable to the extent that the Lexmark my wife purchased, I seriously thought of it as a "throwaway" printer. (My premise was that at $29, use the printer, throw it away when the inks ran out and just buy a new one- a sort of "Bic" lighter approach. I realized later that the cartridges that were initially supplied must not have been filled to the same level as the replacement units.)
As to the availability of refill systems for modern computer printers; the refill systems which I used for many years for my home computer printers do not adequately cover the newer models of multi-cartridge machines nor do they provide the full range of inks. Refilling was fine when there were one or two cartridges and there were no special inks/dyes to consider.
In terms of price savings, reiterating my earlier comments, I purchase through a supplier that offers nearly the same price as a refilled or third-party cartridge through the use of discounting and store-based trade-in of the old cartridge for approximately a $10 package of paper.
The overriding reality of having a messy, leaking cartridge is not one I want to deal with. I would rather pay the higher price to guarantee reliability and quality when printing. I submit most of my work as digital images but when there is a need for a printout, I still require a high quality, stable hard copy. I prefer the safety and reliability of new cartridges based on the philosophy that "it's the cost of doing business" and that "good business recovers its costs."
