I haven't seen anything pre-made, and building it by hand is a pain because there are 20 wires, a pot for the contrast and a resistor for the backlight.
Even finding single row 20 pin ribbon cables is a challenge.
I just want an easy way of connecting to pin 22 onwards (avoiding the SPI pins) on the Mega. It doesn't have to be a full shield.
After a recommendation on this forum, I've been using the old 40 pin IDE cables (not the 80 way newer faster IDE cables).
At the Mega end I break them out into a 20 pin header and solder the wires to each pin. At least I've only got to do this on one end.
I also wire the upper / lower pins for each row together, that way it doesn't matter if I plug it in at the display using either row.

There are at least 3 versions of pin outs so the board would be almost the size of a shield I might try something soon. "GLCD instant gratification shield"
