If you're looking for a reliable all-in-one inkjet with good quality output, a solid warranty and inexpensive ink, look at the Epson workforce, NX or Artisan series. The best warranty in the industry. For a year, Epson will fedex a replacement and pick up the old one should you need it.
You might find the best value direct from epson.com They had the workforce 500 for $60. It is a copier/scanner/printer/fax with auto sheet feeder. I bought one myself. Great machine.
If you want to save money, the NX100 for $30 from Target http://www.target.com/gp/detail.html?asin=B001G8H198&tag=tcom-gbexpo71-20
It's slow and noisy but it gets the job done. It also doesnt have slots for media cards.
One of the nicest features of Epson is that they dont have a separate cartridge for every different model like other companies. There are basically only 3 or 4 types. Most of them use the T069, which means cartridges are easy to find.
You can get 11 free cartridges every month which each hold about triple the ink of Epson cartridges. This does not involve joining a club or mail-in rebates or committing to any other offer. Here are the details: http://www.ccs-digital.com/freeink.asp
