You can find them on eBay, especially spare PS3 laser units. These are readers and so only have a low powered diode, but you might find burners on there as well which will give you a more powerful laser.

Main thing is to build or purchase a driver for the laser. Make sure not to over power it with to much voltage and more then about 40ma will also kill it.

Directions and pages of advice. I built one with moderate success, but it was too ambitious as a first electronics project for someone with little electronics experience. I did learn quite a bit though.

EDIT: Oh no, the pictures are gone!
