I've watched the Coltrane so far, and it's great to see the ALS and the other show which I had on a poor quality VHS boot. The sound is excellent, and the picture quite good. For me the box is a no-brainer. I'd have bought all individually except maybe the Griffin. I have all the full boxes starting with Series 2. From Series 1 I just have Quincy Jones, Monk and Chet Baker, but I've seen the Basie, Ella, Diz, and Blakey from Netflix, and the weak link was Dizzy. It was the bonus discs that started me with Series 2.
