given the overwhelming improved quality of DVD and BD, I rarely will
watch VHS tapes. Still there are films and other material on VHS which have not been released on DVD, so those are worth keeping.
About Region Codes on DVD (Zone on BD(Blu-ray)), many inexpensive DVD players are available which will play ALL regions (see the website videohelp). There also are multi-zone bd players, a few inexpensive ones, more at higher price point. I've had poor results from a number of inexpensive BD players, so if you buy one be sure the seller has a free return/exchange policy.
