Sidssp, Cmalak and Kdibello:
If you read the link to the Oppo web page provided in Cmalak's post, you will see that only BDP-83s purchased before November 9, 2009 are eligible for the SE upgrade.
You might be able to buy a used BDP-83 for which the seller had the purchase receipt - Oppo's web page doesn't expressly say the person requesting the upgrade has to be the original owner. However, picking up a used one might be hard - they are relatively new and none are currently listed for sale on Audiogon. Also, you have to complete your purchase and send the unit to Oppo before the upgrade offer expires on December 31, 2009.
