In MMD 040410 the cost of custom-made music box movement was discussed and it was stated, "That's very expensive!"

I would suggest a very good and cheap solution: Take a Sankyo 20-note movement and punch your own paper strips with your music of choice.  This movement is sold in Germany for less than 40 euros (i.e., less than 50 USD).

This movement is hand cranked, which I see as an advantage (in some respects) because the player can express his personal interpretation of the tune by varying the speed of cranking.  For those who don't like hand cranking, it should not be too much a problem (for a skilled amateur) to add a small spring-wound motor to the movement.

I personally enjoy composing the music (done by a friend of mine), punching the strip (boring!) and playing "my own music" from a small monkey organ wherein I mounted the Sankyo movement.  The organ kit for this small model was sold from a Dutch company named "Authentic models, Holland."  Don't know whether this model is still available from them.  See the attached pictures.
