I never used to think about it, but after 30 years of diving
from simple recreational to advanced research
with mixed gases, I have now been a DAN member
(as an individual) for the past three years. I just recently added my daughter and wife by upgrading to a "family plan" and since we'll be diving in some very remote
and uncivilized locations, I like the added security
and peace of mind just knowing if something happens I can get an air-lift for "free" to a chamber for anyone of us.
In my opinion, YES, it is worth it, but only if you use it once. It's like insurance
, don't like paying for anything you don't use, but damn glad to have it when the bill collector knocks on the door for dollars and you're trying to save pennies.
