Well, back on topic, I think I have a relatively sizable collection, not nearly comparable to others on this forum though. I'm not going to list all of them but just name some valuable ones. These are my official ones... I'm not bothering to count burned stuff:

VHS- 49 (Matrix "For Your Consideration" Screening Tape and unopened "Jailhouse Rock" colorised)

LDs- 86 (Magnificent Ambersons CAV LD with full bonus features, first issue of Blade Runner theatrical version, Alien with 70mm mix, North by Northwest Criterion set, Lawrence of Arabia Criterion CAV, From Russia with Love CAV Criterion with commentary)

DVDs- aprox. 1,000 (Evil Dead II Tin, GOUT Trilogy, A Hard Day's Night MPI Version, MGM Army of Darkness HQ Director's Cut, Time Bandits Criterion, Tron 2-Disc Release)

BDs- 312 (Evil Dead original 2-Disc issue, Dr. No and From Russia in Collectible Tins, Pulp Fiction Polish BD with visibly superior VQ to US BD, Big Blue)
