Here is another option:

It says 5V logic / -20V drive on it ... does that mean I need to supply both, or are there onboard regulators ... this is confusing the bejeezus out of me.

My Powertip draws about 35mA typical on the +5V line (not including the backlight current which is 120mA in my case).
A 500mA to 1A power supply should be largely sufficient but be sure it's voltage regulated (most cheap wall mounted power supply aren't...). The tolerance on the +5V line of LCDs is maximum 10% (4.5 to 5.5V).
About this LCD:
- It's only 240x64 pixels.
- It doesn't have a builtin negative voltage charge pump, so you need a separate -20V voltage...
