I got my black/white KB from Cellular Accessories - LG, Motorola, NEC, Alcatel, Dopod/O2, Nokia, Sony, 3G, Apple, HTC, Panasonic, Be
for about $6
Installation was super easy following the 8800 disassembly instructions on the BB FAQ. Some comments. First, the screws are T4 or T5, not T6 as described in the FAQ. Home Depot sells a small Torx jewler's-type driver kit made by Husky for about $6 that will do the job.
The plastic pry tool is a gotta-have. Don't even try this without it or you will butcher the side panels.
You do not need to take the unit apart as the keyboard will slide out the bottom once you get the side panels all the way off. (stop at step 3)
My 8830 had the tops of the side panels (screen half) glued on with some two-sided tape, so it was necessary to apply a bit of gentle persuasion to get the panels off. The tape stayed in place and was still sticky; the unit went together just fine.
Total time: 10 minutes.
And now my old eyes can see the keys!
Function beats the snot out of form every time.
