Held every 2 years. It's good if your in the manufacturing trade etc or have a pro workshop.
Some of the machines they have on display are massive. They tried some years ago to incorporate the hobby diy trade, but it didn't attract the numbers so it was ditched.
The recession hit the last show which brought about a slimmer show plus the cost of show space etc etc.
Personally imho it's a good show, aimed primarily at the trade.
