With the cost of printers, copiers and scanners so low, why not just buy an all-in-one for under $100, where you get almost full ink cartriges included - the cost of the whole package is almost the same as a pair of ink cartriges!
If all you want is a copier, for office use - why not just print multiple copies off of your printer - you can scan copy in, perfect it, then make as many copies as you want.
Hope it helps - however, if you can get a used copier, business class, for the same cost (or refurbished) as a new 3-in-one printer/scanner/fax, then choose what you will ise the most.
