Fredric at Coralreefbazzar sells them somewhat locally. http://coralreefbazaar.com/product_i...products_id=94 Just wish his browsing feature was simpler. You'd never ever know that there was a store on the website.

WHat do you need it for? I have several other ballasts that may work. 2x26w/1x42w Advanced units. A friend has several others.
