I recently got this "Perfect Miles Davis Collection" set which is almost like a condensed version of the "Complete Columbia Recordings," only twenty albums but the trade-off being the price (third-party sellers on amazon around $40). http://amzn.to/Oqttid

Packaging-wise the individual sleeves within the hard box are slightly below the 'mini-LP' cardboard sleeves that you get with some Japanese CD reissues, but better than the cardboard sleeves you get with 'Original Album Classics' or 'Proper Box' sets (no plastic/paper envelope, but smooth insides so small risk of scratching from typical handling). A booklet containing brief liners for each of the albums. From what I gather the discs are what you would have gotten with the standard issues, so they may have whatever bonus tracks are typically on those but not, for instance, all of the studio chatter and live stuff on the Kind of Blue Deluxe.

Was a good deal because, although overlapped some with my existing collection it would be a LONG time before I got around to hearing all twenty of what was included, some of it perhaps never. Great for someone like myself who still has a lot of learning/listening to go. There are omissions, but cheaper relative to the complete Columbia set, plus I like the immersion.
