Wireless Multifunction Printers

I seek feedback on the Canon wireless ikjet printer MP600R, the
wireless Brother 685CW, and the Lexmark WiFi

My main criteria are (a) separate ink tanks but no more than Bk,
C,Y,M, (b) clarity of text output (no feathering, crisp printing), and
(c) cost of consumables.

I'm not intersted in printing photos.

I've read poor reviews on the Lexmark and and the brother, and rave
reviews on the Canon, but would like feedback from buyers of these
products.
