There's a cheapo Sony version that came out a few months ago, I'm sure it was discussed here.
It's perfectly legit, and I think it even has a small booklet with the discographical info (but don't nail me for this, I have the big box!). It's a "wallet box" or how they call these, cardboard box the size of a regular CD, more or less, with the discs packed in cardboard (or paper) sleeves. Nothing fancy, just a great way to sell the music cheaper to those who wouldn't go for the expensive big box! However, there are several Spanish and Italian versions around (Comet is one, from Italy, not sure which of the Lonehills/Jazz Factories etc has released it in Spain).
