Is it true there are no longer parts available for an XDT4 transmitter?  Claumi posted 2 weeks ago and was advised only on Ebay?  I just purchased this system brand new less than a year and half ago.  My transmitter works but someone stepped on it and the plastic that holds the metal clip has broken at both attachment points..  This renders the transmitter useless unless the use of some sort of tape works for you but not for me.  Any help on this one?
