I may have to upgrade to this release...
I read that there is a commentary with Romero and Savini... and read this is THE version to have... at least in R1 land.
I also understand that the Divmax release is the best available (except for the Bklu-ray, of course
) and the one I own myself (the Blu-ray was a double-dip). But, don't buy it for the commentary as Romero cannot talk about his films unless moderated (and no, the feloow filmmakers are not moderators). Not that he is boring, he just doesn't know what to say about these 20 year old films. The other extras are mostly quite good.
The worst Romero commentary I have listened to must have been the one I had on the Japanese laserdisc of Dawn of the Dead, where he talks with his wife (she's in it, in the opening scene, setting next to George). They were silent half the time, not knowing what they could possibly say about the masterpiece.
