I ordered it as well and it arrived today so I can't fault the speed of delivery
So I took some scans of it here:
FAKE N900 Keymat from eBay:
Front


Back


Hmm... the fonts and the printing of the fonts
Keymat feels quite solid, I shone a light from the back of the keymat and it does appear to light up the keys.

As my n900 keypad is not faulty and I'm not going to rip it out to find out if it installs okay, maybe FP125 will be able to report back on that.
