Orders/Alibaba 122x32 LCD Displays
Organised by Sci.
I've been quoted $7.50USD (so about £4.62 each) plus about $35 (~£22) postage to the UK for the 4 I'm after.
Price might go down a bit if people are interested. I don't know the price-break quantities though.
Revised postage will be $60, plus $9 bank fees. Across 22 items that's a $3.14 (£1.94) fee per unit. Totals per interested party at the bottom.
Lead time is currently 1-2weeks while waiting for new lot of red backlights. Delivery time should be about 5 days from then. Will be notified.

Order has arrived at Sci's home address. Will attempt to deliver them to individuals member-boxes at the weekend unless otherwise instructed.
The controller appears to be a SED1520 module. An AVR library is here: http://en.radzio.dxp.pl/sed1520/

The backlight is provided by an LED on each side of the display. Looking from the front of the LCD module, the top-right and bottom-left pins are +3.3V, and the top-left and bottom-right pins are connected to ground. The datasheet is inconsistent, but suggests either 15mA or 40mA of current per LED.
