Laser pointer diode

I was making a laser trip wire, but I was looking online for diodes which I found, by which one would be best to get, I dont care for the color, in fact I am better off with red and the intensity can not put off heat to harm anyone. Anyone have any laser diode recommendations or have a site that I can buy them from?

May be cheaper to just buy laser pointers and extract the diodes... There are some cheap ones at amazon.com
There are some cheap ones in Dollar stores now a days :-)
