My telex 750 is for sale. Used approx. 1 year. I replaced it recently with a Telex 850 which works a little better for me in the Q 400. It is in perfect condition but missing the foam over the mouthpiece which I am sure you would want to replace anyway for sanitary reasons.
$75.00 plus shipping, any interest? If so, PM me to work out details.
Thx,
