The 4CD sets all came with very simple card slipcases holding the CDs together. They were sold for about the price of a normal album. As each CD in the set had its own catalogue number and barcode the temptation for retailers was to split the sets, hence few complete sets now remain. I am not sure if the label also marketed the CDs individually

To the best of my knowledge all these "Best Of" albums came as four-disc budget compilations in the mid 90's. Fortunately for us, all had seperate cat No's despite being box-sets. It appears that few of these sets remain intact.

Another advantage is that most tracks were full-length and unmixed. With the rising interest in 'Old Skool', these comps are becoming quite collectable.
