I have been thinking about getting a portable continues flow(2) oxygen compensater. I was so dissapointed when I was told that they were phasing them out because they weren't very dependable and they kept breaking down. I have searched and searched the net and could not find anything about that. Has anyone out there heard of this. And do you have a portable continuous flow compensate r and do you like it....would really like to know it would solve a few problems. Thanks Dianne
