Yourmusic.com has this set for just under $24, in case anyone wants to pick it up before it goes OOP.
If it matters, my guess is that the Yourmusic.com version is not packaged in the format with the CD sleeves and booklet bound into a small hardcover like a book (as the Pacific Jazz Gerry Mulligan Quartet recordings were as well). When I got this set from BMG several years ago, the CDs were in a "fat boy" 4-cd jewel case with the jewel case and a separate booklet inserted into a cardboard slipcase.
I got my "dandy" booklet bound into etc, as you describe it, from BMG. I suggest the same is available from Yourmusic.
