What All-in-one would you guys recommend? I'd like to go somewhat inexpensive, and haven't bought a printer in a very long time. What is good to buy? and Mac compatible, of course?? i like what I see here http://www.shopping.hp.com/webapp/sh...ail&aoid=21496 but would like a wireless option, if possible. what do you look for when buying one of these things? I suppose they're all fast. What about noise level? I think I'd like dual sided printing. I'm just looking for general use.
