In the neverending 'should I get ink refills or just get a new printer for a few bucks more' dilema:
An interesting long term evaluation of 3rd party inkjet cartridge providers vs. the manufacturers looking specifically at their fading qualities (earlier in the series they show that you can use some 3rd party brands just as well as manufacturer for the same print quality). Now you all know that the expense of a laser printer pays for itself in a very short time, right? (for b/w anyway, even though the same is true for color, just less so) :)
