Hi Roy.. I have 3 green laser pointers in several powers. I purchase mine from Scales Plus in Western Australia. The guy is very helpfull and I placed my orders over the phone. He has a wide range of type and supplies Laboratory Use, Observatories and Astronomers.
Here is the link to the Web Page

Give him a call as he has other options other than what is listed on his Web Page.. Here is his phone number 0411.637.447 as listed on his Web Page.
Hope this is a help to you. I had all sorts of trouble getting what I needed and this guy was great.. Not sure what state you are in, but often the membership to an Astronomy Club is all that is needed to be legal. You will need to look into your own State Laws as they are all different...
Regards
Mardy
