I would recommend a
beier usm rc2
I have 2 of these and they work great, take a bit of setting up on the computer to work how you want them to though.
1 is in my
JD9530
the other is in my
944B
you can copy a sound from youtube and edit it to suit your needs, also if you email beier they will create a sound file for you.
Surprised you havn't come across them already as they are German!
Hope this helps
