Those are some pretty good specs, .67 height is quite good, but my only
challenge is that I _detest_ red displays, and other colours always draw
more current.  Oh, well, beggars can't be choosers, I guess.

Yep, he means HP.  Here's some specs from the Allied catalogue:

HDSP-H101
Color                           AlGaAs Red
Typ Intensity Per Segment       700 ucd @ 1mA
Dimensions                      .67"H X .49"W X .31"D
Price                           $2.47.
