I just bought the 605 for 303 total with the shipping....You still get the 1yr manufacturer warranty and they may not necesarrily be "refurbs"
This is the response I got from ecost upon asking about the recerts
Manufacturer Recertified are returns
of defective, buyer's remorse, and for online stores could be returned
to shipper or simply refused upon receipt. These products are sent back
to the manufacturer for scanning and/or repairs and are re-certified by
the Manufacturer to work like brand new. These are then packed and
sealed for Manufacturer Warranty.
Either way though...if you can get a brand new one for $50.00 more then that may be your best bet
No shipping or waiting
