It sounds like I can count myself lucky. I got it over the holiday for $29.95. It is a well executed set. There are some excellent special editions now coming out of Korea. The book is in both Korean and in English.
For those who missed the limited edition box, I think that the DVD only (same as in box set) can still be purchased. I have not watched it yet, but the film appears interesting in its concept and unusual execution. Based upon sampling, the transfer and sound are just fine.
