Sorry David, didn't mean to put words in anyone's mouth by "slamming" one product or another. Not my intension at all...
The fact is the JMP unit is kinda' new and nobody seems to know much about it. Just wanted to shed some light from what I heard. As I said, I have absolutely nothing to gain by promoting a tank over BVM's or anyone else's. The fact that I have 2 BVM tanks and I am very happy with them both should be enough proof.
If I'm a little long winded its because I'm an engineer, unfortunately we all like everything into 50 decimal places...
Later,
Kelly
