Apple has started selling refurbished iPad 2's...
Clearance iPad Accessories - Apple Store (U.S.)
Apple "refurbs" carry the same one-year warranty (AppleCare can extend that to three years) and the quality is always "as new" condition. They replace the screens and the back cover so no one will ever know. The only real difference is that they come in unmarked boxes.
I've purchased a number of Apple refurbs and all have performed flawlessly.
They have 32GB and 64GB WiFi and 3G iPad 2 models (at the moment) for AT&T and Verizon. They also have 64GB WiFi only for $50 off of the price of a new model. Black or white...your choice (again, at the moment).
So if you've been waiting...now's your chance!
