Printers

I'm thinking of getting a new printer. The one I have now does well for printing word docs and some pictures on full sheets of photo paper, but I'd like a multi-function printer.. and the wireless connectivity is appealing.

So I hopped on over to Amazon and found a couple of choices:

The HP Photosmart C7180 All-in-One Printer, Fax, Scanner, and Copier

or

HP Photosmart C6180 All-in-One Printer, Fax, Scanner, and Copier

Basically, they're both pretty much the same, even the price. The 6180 has an autofeed tray and a different interface/control panel.

The reviews seem to be about the same too, so I'm not sure which one to pick.

Help!
