Superstar DM-5000, thoughts?

Has anyone attempted using the DM-5000?

If so, what do you think of it, worth the coin?

Also, the recorded noise "feature", are you able to employ that as a roger beep or is it something which keys up separately?

I can see the later being useful in eliminating overpowering beeps which you hear on both ends of radios such as the dx55hp.
While I enjoy having a mild tone to confirm end of transmission on channels which may be "loud" for lower end radios lacking an RF dial, the "BA-DEEP" emitted from the Galaxy cooks my brain in short order.

It isn't as loud doing rx tests on other units, but as the tx, ouch.

 

It does give the impression that a two thumbed hand might be required.
