680nm laser diode?

[trever22]

I never knew there was a such thing until now LASER DIODE 30mW 680nm Blue Sky CircuLaser diodes 9mm - eBay (item 190444294022 end time Jan-11-11 13:57:48 PST) But anyways is it a good deal? does anyone own one?

680nm would be very, very dim. Even though that diode would probably be of excellent quality, it'd be very dim and a waste of money.
