This is in Taikoo, but I noticed that Apita had two modesl of Canon printers on sale- one was a dedicated high quality photo printer, and the other was one of the more basic MX (multifuction including fax) models.
I've bought a Canon MP648 after some recommendations on this thread: http://www.geoexpat.com/forum/thread68925.html. I'm quite happy with it- print quality is good for an inkjet, it does duplex and the user interface is very simple. I've not had to deal with ink replacement yet. I bought it from Fortress- couldn't be arsed taking more time to try knock a hundred dollars off, and Fortress does free home delivery so I didn't have to lug it back with me.
In the Canon line, I think that if you want wireless, you have to start towards the high models in the range, so you're looking at start prices around 1500 instead of sub 1000 for the more basic models. Frankly, I'm not convinced that wireless is such a useful feature in a small device which will never move, but I guess it might make placement easier in some situations.
