I've done business with Z1 and defended them at times in some of the Z1-bashing threads... But it IS a pattern of theirs to be absent until someone comes on here bashing them, and then they magically appear. Even those that love them can't deny that.
I don't have a problem with you or Z1, just pointing out a similarity in cirumstances.
I look at this type of drama as simple entertainment. I've given up on serious responses to this kind of thread. :-)
