Watch the second link, thats a Front Mic.... Yea you will have a tough time with an original.... the 3900 ones work ok, a bit on the cheapie side.... Obviously the front mic in the second link is about useless.....
Only real practical choice is the 3900 bezel, or watch for NOS....
I lucked out and picked up 2 NOS grant face/bezels, guy had 20 of them, ALL gone now, they sold for 11-50 dollars, I managed to snipe both of mine, 11 and 15.00 Wish he had more... Also a PITA to find decent black cases, most of them are like the 3900 bezels cheaply made...
Good luck in your search, if I run acrossed any I'll update, my search continues.......
