Yep, we had this discussion just the other day and I was starting to think
that I was going to change from my constant flow system to the EDS.

This thread has caused me to decide to keep my current system.

Oxygen is relatively cheap at my field, my bottle is good sized and the
whole battery issue is a non-starter.

There really aren't any battery "issues"; these guys (including me) are
just arguing about the right guilding for the lily. Put the battery in,
turn it on, and use it. The EDS does provide automatic operation and
some audio and visual warnings that a constant flow system doesn't
provide, so it might be safer overall. But since oxygen conservation
isn't of interest to you, I'd say keep your present system and use the
money saved to buy an oximeter so you'll know your system is working for
you.
