No kidding, from what I heard it's pretty pricey.  Of course my life 
is worth more, but still, it's a bit annoying.

On this subject I wanted to ask a question, maybe someone here can 
answer it.  Let's say that (to make it simple) you are diving a mix 
with 40 % He and 25% O2.  After your dive, you come up with 1500 PSi. 
Now you think, ok, I'll get a 25 % nitrox fill to make it 20% He and 
25% O2 .  What happens when they hook you up when the compressor 
reads 700 psi and they've got two other tanks hooked up?  Doesn't the 
gas flow all over the place?  Do you still end up with your He 
content, or not?  And how do you check this, if the O2 % is the same, 
you really have no way of knowing.

So, do you have to make sure that the compressor reads a higher PSI 
than what is in your tank when they hook you up, to insure that flow 
is only in one direction?

Thanks.
