I bought my gauges from Innovative. They also sell any type of pillar you are looking for. Their prices were the same as anywhere else I found. You will have to paint the pillar though. as far as I know they only come in black plastic.
as far as the gauges I got the Autometer Z Series. They have a black face, white markings, and a red pointer. Three gauges and pillar cost me roughly $300.00
