Not too late yet.  I'm planning to order very late today - in time to 
get shipped before the weekend from China.  I'm hoping we can have these 
suckers before the end of next week!

With Sean's extra 10 units and your $50, we need at least 12 dozen now, 
which is awesome, I've always wanted a gross of lasers.  I wonder what 
the flock term for lasers is, perhaps a "blind of lasers"?!? :-)
