Well it is pretty easy to get around and you can have a Green laser as large as you like.. I have done this several times and own a 100mw, 80mw 2x60mw and a 30mw... If they ever change the laws again I have all I need... Now on to the how too part:
Firstly if you purchase a green laser module it is considered a part and gets through customs no worries. Do a search on the Bay for 60mw Green Laser or whatever size you want.. they cost around $25 upwards dependent on size... You must purchase the ones with a spring at the end and a button on the board. The button on the bord lines up with the button in the tube for on and off. Dont worry if it has a red and black wire as these you will just cut off. Here is an example; Item number: 260816809620 Thants part one done....
Part two requires you to purchase a Red 1mw laser pen that is the correct size to fit the Green Laser module into. The purchase of a 1mw Red laser is also perfectly legal... Here is an item number of the correct size Item number: 300606512613 They are the black cases that have small dimples in the grip.
When you get the both items as you will.. You just pull the end off the tube at the laser end with some pliers and then tap out the red laser with a punch or a bit of down.. Then press the green laser insert into the tube in it's place lining up the button and hey presto you have a green laser for around $30 - $50.. And a powerfull one at that... Work well for me and one of my friends...
Rules are just thier so you can find constructive Legal ways around them... The funny thing is that I have never had a green laser module seized but I did get on of the 1mw lasers taken of me as it was not marked 1mw so they took it to be sure... Work that one out LOL
I hope I have been some assistance as I find this new set of laws a big problem for the Astonomical Community. A few fools that mess things up for others... Hmmmm
