James,
I have one sitting in my garage unused you can have for 10 euro (to cover the cost of my toll and petrol). its only been used twice as I found that the Co2 always leaked out of the keg. Its missing its bulb holder as I gave it to a mate for his king keg. If your interested let me know and I'll see if he's using the bulb holder, if he is I'm sure you can pick one up about the place they seem standard. I'm living in Mullingar but i'm about Dublin most weeks.
