I'd recommend staying away from Lexmark. With all printers, it's the ink that's expensive. With my old Lexmark, I put a new cartridge in, and within a day, it would tell me I needed a new one. After that happened twice (and hearing it happened to a couple of friends, too), I decided I would never get a Lexmark again.
Now I have an HP all-in-one (scanner, copier, printer). Works great, and isn't too bad on the ink.
