I pre-ordered R3 HK Edition from CD-wow.net for $15.95 because their prices, which includes shipping, is hard to beat.

The next one to get would be the extended Edition fro R3 HK.

Besides, considering the amount of money I have to pay to get any version of the movie, and how much they are in the place of origin, I think that only getting R3 HK edition is not getting ripped off.
