Hi,
maybe if they made a top quality vocalizer optional instead of including one that's apparently is not really suitable for professional use.
Maybe players requiring a vocalizer wouldn't baulk at the additional cost, for the added convenience of having an all in one unit.

If it was removeable ( like the expansion boards) and able to be used again in the latest model, that would be better still.

Probably not a feasible suggestion, but one never knows.

Some of us paid a fortune for the convenience of having an optional hard drive.
( me not included, I used to be happy with the floppies, as it was only for home use).

best wishes
