I've had an idea for some time for a photography project that involves a blue laser. Previously when I looked into it, they were too expensive, then the 445 projectors hit and I assumed in a few months there would be all manner of inexpensive blue lasers around. But checking in it looks like all the action is in the ~500mw and up range.
So if I was looking for a cheap (say <$70) blue pen, what are my options right now?
Thanks,
