We seem to get this thread every year. It depends what you want and expect. I don't know why people think they will get a bargain at events like this, you might, but the traders have to pay for the stand, pay for extra staff, etc.
I wouldn't go every year but when I do go there are a few things I get from it. There are some good and inspiring talks, most of which are in the ticket price. There is the chance to see what's new, and that's not just the big brand bodies and lenses, its lighting, bags, accessories, gadgets etc. - you might just find the perfect bag or a gizmo that you really can't live without

If you are in the market for a body you can get your hands on all of them and see what feels right.
It does what it says, it's a show, a festival, an exhibition. If you enjoy all aspects of photography there is something there for you.
