Casio CZ/ VZ/ FZ - Pro Series

If you do a new poll, include the Digital Horns.  I know there's a 
100, a 200, and another one or two.  Also, have a question for DH 
owners: 

Does your digital horn have the infamous squeal problem?
( ) never had the problem
( ) had the problem, but got it fixed
( ) still has the problem

PS: I've been here for a few years but never knew about the poll!!!
