I got a green laser from dealextreme.com in Hong Kong for about $25 with free shipping, they are awesome. I'm spending the week in Kauai, Hawaii and the night sky is amazing, I brought my laser with me and it has been fun to point out the stars & planets to my family. I have always been an astronomy enthusiast, our wedding was under the dome at the Minneapolis Planetarium (in my kilt) and then we did a private planetarium show for our guests. There was a photo of us printed in Sky & Telescope magazine.

Tree trimmers are starting to use the green lasers to show customers what branches they intend to prune.
