Yeah I see it in the UK on a lot of monitors at the Manchester (Bowlers) shows and they are regularly in use at all the Northern Computer Markets,

they used to have a yearly pass for those fairs but they get about 15,000 visitors a day now so they stopped the yearly passes and charge £4 to get in (Robbery) and man the queues are huge,

it's all gone off in the last few years used to be lots of cheap parts to build and sell from but now it's all mobile phones and DVD films (don't mind those too much)
