UK Equivelent of CAX?

Is there are UK Equivelent to CAX, I would love to go but it's very far and would be very expensive.

I think that the UK Pinball Party is what you're looking for. In a couple of weeks! In Northampton. I'm thinking of going!

@bibamatt: That does seem cool, but I'm not really into Pinball machines that much.
