Found a whole pile of Prima Chocolate fountains, the twin chocolate one, so you can have milk and white chocolate running at the same time! :)
they are priced at £49.95 originally then ,marked down to £20 with another 50% off that
Bargain at £10!
sorry coudnt find a picture of what it looks like exactly, but this is similar, except the prima one has a partition through it to keep the two chocs seperate.
cant see it online, must just be instore.
