the thing is, with cheap ass printers, that they cost more in the long run. reasons:
1:the color cartridges are often combined in one cartridge, meaning, when you're out of blue, u will have to replace the cartridge, and with that u will also replace the red end yellow although there is plenty of that ink left in the cartridge. printers that cost a little bit more usually have separated colors.
2: they usually use more ink to print the same thing.
what I wouldn't do:
first of all, I wouldn't buy a brother. My girlfriend has one, and you have to replace the cartridge as soon as it runs out. problem: say I realy need to print a document urgently , and say i'm all out of red. the damn thing won't print because red is empty, although I only need black. I don't know if every brother has this problem though. what bugs me even more is the fact that this actually happened in real life; but the red ink wasn't even empty! the cartridges have this chip that says how much ink should be left, but this is by no means accurate.
what I would do:
I bought myself a canon. they use little ink and even the cheaper models have decent print quality.
my two cents.
