This ebay seller has the EU version of UNDER DEFEAT HD DELUXE EDITION PS3 for around ~$10 shipped, which is about half the cost of the US version. The PS3 is region free (ahh.. for the most part, Persona Arena is the only exception I know of).
Also, keep in mind the seller is based in the United Kingdoms and this game is the EU version.
One more thing to note, paypal charges a currency conversion fee.
If you have a credit card with little/no currency fee, on the payment page, select the option to pay in British Pounds (vs American dollars).
And no, this is not my listing.
