[Laser] super PIN photodiode sale!!!!!

[Buchanan Bill]

Yeap all of the pd-3 and pd-4 photo diodes from All
Electronics source are gone....BTW see that Steve is
back again...wonder what you think of the K3pgp
frontend?....Also might mention that activity here on
laser is quite low at the moment, but hopefully that
will change as summer comes on....
