Daz,
I am an instructor at kamon, so I'll give you a completely unbiased view.
The Eastbourne Kamon class will be the bestest awesomest martial arts class you've ever been to!
Just kidding
The training is good and each instructor is handpicked by Kevin Chan for their background in other arts, responsible attitude and streetwise mentality
Bear in mind that each kamon class is different and will have something different to offer. If you pay the cross training fee, you can also get to the other Kamon classes in your area
My advice is to give it a go for a month and see if it is what you are looking for
