If they don't make your cartridge easy to replace, then refilling is a viable option. The local discount grocery store (Save A Lot is here in North Texas, and I don't know where else) carrys them cheap, so refill is a no-brainer.

A professor friend told me years ago, when I was contemplating buying my first laser printer to print my thesis, to look at the printer cartridge and do the math on the number of pages and the cost per page. In doing that it was easy to choose the HP and go with their larger print cartridge. I don't refill the laser cartridge, though they are refillable. I do recycle them (I can take these to the Mail Box/UPS store locations in the area and they will ship them free of any charge to me).
