I read this recently in an article from a magazine...
Jaycar sell the green 10mw modules listed in the 2013 catalogue. Buy a cheap red low power pointer and swap the module over or customise your own holder.
China also sell the modules a lot cheaper on Ebay... search for green laser module. Hint... get a friend who works in a scientific work place or university as the send address and hopefully customs wont intervene.
Sorry but cannot exactly remember the mag this info was in. ;-)
Make sure though you know what the laws are for your state. In some states, you need to be a member of an astronomical society or have a gun license.
