If it's only a single location (or multiple switches that control one light) you could use a Lutron Spacer. This works well for me, but it's not as sexy as the clipsal. Look here: [Link: store.yahoo.com].

You're right, that is a good price on a 6000.

EDIT: I noticed the clipsal was rated at 240 volt, the spacer is a 120 volt switch.
