I'm no expert but isn't the needle valve more important to prevent the EOTD, since it ensures consistent flow over various pressures?

The "good NV" idea is saying that regardless of pressure the count wont increase or decrease? I'm sure it's possible, but how it does it is over my head.
I though EOTD was brought on by the regulators inability to handle the difference in pressure as the tank empties. Hence the shift to dual stage and not simply dual gauge.

A good needle valve will provide consistent flow with consistent pressure. (not so good needle valves can travel so do not provide consistent flow) If pressure is increased/decreased on the input side of the needle valve then flow will increase/decrease also.
The only way to eliminate EOTD is with a dual stage regulator. (provides consistent output pressure even when input pressure changes)
So if you want to run your CO2 tank till empty with no EOTD and have consistent flow, the best option is dual stage regulator and good needle/metering valve.
Ahhh too much consistency... (use of the word consistent)

Does anybody have an opinion on how the Micromatics regulators compare to Cornelius regulators? Beveragefactory sells both, the Micromatics being more expensive. Does this mean it is a better regulator or are they more expensive, for looks and a fancy knob?

None of the above - Victor, Concoa, or Matheson dual stage with a good needle valve - as in a swaglock or Burkert not the cheap stuff.

Sorry, I'm not wanting a 5 lb regulator, don't need it because I've never had an EOTD and I run my CO2 empty all of the time. I'd rather spend my money elsewhere. I was asking for an opinion or comparison of a Micromatics vs. Cornelius. Thanks.

I agree on the Ideal or a Swaglock needle valve. Between a dual stage reg and a good needle I've never worried about eotd's and I always run it dry.

Agreed, but I think the Ideal is better and more fine "tune-able"
I have the Swaglock as well but the Ideal takes the cake.

Have you seen the Swaglock's with the vernier caliper handles? that's what I've got and it's as easy to tune as my Ideal tho that's the only type of Swag I've used.

This statement implies that if you do not have a dual-stage regulator you will have an EOTD.... that simply is not the case.
I agree that a dual-stage regulator will help to prevent the possibility of an EOTD but have yet to see any evidence that it is a widespread problem.
