I just got one for $39.99 last week
Amazon Kindle D00901 Wireless eReader 3G WiFi eBook
"Condition: Pre-owned, Included: Amazon Kindle 3g + Wifi"
looks pretty sweet to me; can't find a scratch on it even though I had to order
"Product Grade: 5 - Some scratches and/or signs of use"
Of course, Not Included: Ac Power Adapter, Usb 2.0 Cable, Owners Manuals and now I see Staples might be clearancing the adapters for $2 (YMMV).
Not disappointed at all - just waiting for the adapter so I can use it. (This is my 2nd Kindle keyboard... granddaughter borrowed my original... don't think it'll be returned.)
I'll use my phone's adapter or usb cable to charge the kindle, so I don't need a new adapter.
