Rather cheap... until you realize that the price is mainly for the unique box, instead of the whole original edition.
In fact, at one point many years ago there was a similar auction and I did consider buying that box when I saw it being sold for like 70 eur, thinking it was rather cheap... until I realized the swapped CDs thing. A shame, really.
... then again, this box is something
I'd definitely pay a good money for (nothing too exorbitant, tho') even if it had none of the CDs.
