Thanks for your response, I am looking for a matching pair of ballasts.

your not interested in a dual ballast? has to be 2 seperate ballasts? im not selling, just curious as i am running one and love that it only has one plug.

A dual ballast would be perfectly fine. :) If I have two separate ballasts I would want them to be the same brand/model, and same age so I get the same color out of the bulb.
