Ink cartridge and per-page costs can also be compared. pcmag.com, pcworld.com, cnet.com, macworld.com, etc. all have reviews, and some break out these costs for you. Some cheaper printers end up costing more per page when replacement ink costs are factored (however, if you won't be using your printer much at all, a larger-volume/more economical cartridge may dry up before you have a chance to use it all, thus making smaller cartridges a better option). You can also go to a retailer site like inkdepot.com and compare ink cartridge prices directly; some list the ml content or estimate the number of pages/cartridge.
