Wanted: 405nm laser module and driver

Hi all,
I am interested in purchasing an inexpensive 405nm laser module and driver. Prefer it not to be in pointer form due to legal restrictions on laser pointers in Australia.
Please let me know if you have something of interest. Intended use is for demonstrations in Physics classes.
Thanks!

you could get an aixiz module with a PHR diode and "rckstr" driver. That's probably what someone will sell you, just wait for an offer. Around $25-35 is the usual offer. Input voltage will be ~7.5 to 12. Below and it will not work, above will break it.
