One of the things that people so often forget about buying a printer or fax machine is that the actual box itself isn't the important point or cost. It's actually the ink or the toner that will cost you far more over the life of the machine.
In fact, many manufacturers actually sell you the machine at a loss, so as to get you hooked on buying their ink. There's plenty of basic printers out there where they sell you the printer, plus the ink jet cartridge, for less than the cost of the replacement cartridge.
So what you actually want to do is be very careful about where you buy your replacement supplies. One extremely good such place is Inkers, where you've got a huge inventory to choose from, great shipping and even better prices.
Given the way that the whole industry works, you owe it to your self to look for the best prices on these things and Inkers is about as good as it gets.
