The theatre I work for is currently pursuing new wireless com to replace our aging Telex BTR-700 unit. We initially pursued FreeSpeak, and it has some very exciting features, but we received less money from a grant than we had anticipated. We are now looking into HME DK410. Another local theatre uses HME DX200 and I've had some mixed reviews from crew there, the TD loves it. Any insight you could share about HME wireless com would be much appreciated.
