Hi Alan

I thought somebody will have a go at my ESDc (it's fine; apart from the bag
costs hurdle) ;
you must know the cheap big shield bags source ; can I have it please ?

The other consideration is the diligent medical folks scrubbing (and
charging ) the machines with the hypothetical fox tails .
So be gentle on me ; I know this problem looks dumb ; it's the field more
than the floor .
What I'm basically after is a sort of p/carbon without the build up
tendencies .
Another point is some of the models have an oxy options and good static
materials selection is desirable .

Thanks anyhow
