Smallest 7-Segment Display

I have been looking for a small 7-Segment display for awhile. TDSG Series from VISHAY are among the smallest 7-Segment Displays I can find on the Internet. The character height is only 7mm. They are available at Mouser with mouser part # 78-TDSO1160 for common cathode and # 78-TDSO1150 for common anode. The price for one unit is $1.27. Actually, I found another small 7-Segment display, 7S-1 Super Tiny 7-Segment ($2.99). But, it is a vintage display (New Old Stock) so the reliability is questionable.
