[Len Sabatine]

     Refering to Jameco , They have a Futaba VFD 4 Digit w/ Colon.
     @ $1.99 , US .
     These are easy readable in nearly any lighting conditions and connect
     like LED Displays.
     Part # 42112. Product # 5LT43. There's display I.F.Ckts floating
     around , but that's not my area of expertise.
