Where have you been buying your ink cartridges? If you are buying them at ... say Staples, or Office Max or other retail outlets... you would do much better buying OEM cartridges on Ebay.

I've purchased used laser printers locally on Craigslist just for the four ink cartridges and imaging drum for my HP2550 and HP2500 laser printers ... for far less than what one cartridge would cost me at the retail store.
