The Crickets were tested on the DeVilbis MC (5 LPM at 8.5 psi) and on an Invacare (5 LPM at 5 psi). I sell both of those concentrators. They are $375 plus shipping. Right now, my current supplier does not ship outside of the US, but I am working on adding another supplier for international orders.
ETA: Wally at GTT also tested the Crickets on an M-10 (the same thing as the EX-10) and what he found was that the DeVilbiss he used ran the Cricket better than the M-10. He tested the actual pressure output of each machine as it was running the torch (he ran the lines through an in-line pressure gauge) and found that while they were running, the DeVilbiss was pushing more pressure than the M-10 was, even though the static pressures were different.
