At £14 per month it's a real bargain for unlimited use of such a fantastic site and they really want new members to help make the project viable long into the future. With such a great second hand kite market on places such as ebay this extreme sport can be a bit of a bargain compared to others such as snowboarding or paragliding, you could prob get started for £200 if you chose carefully and others are always willing to let you try out their kites too. Although latest new kit and a 'quiver' of kites for different winds sure can add up!
I'm pretty sure if you wanted to come along for a taster you could post on their facebook page and you would be welcome http://www.facebook.com/groups/294964893946838/
Here's a couple of snaps I took of people whizzing up and down
and if you get really good it can lead onto crazy stuff like this, video shot at the club by Ben Davies
Let me know if anyone wants to come along with me to try it out, cheers, Tom
