Hi Rebncosh,
If you can at all afford it, buy the new stuff, it'll be worth something when you go to sell it, not to mention it is waaaaaay safer and more user friendly and the wind range of one kite is similar to almost two kites.
Come up and see us about 10-15 minutes north of where you are and you can check out or even hire our range of 07 gear (Flows and DNA)with appropriate training

Advice is free all day long.
Also have a look at our website, specifically the FAQ page as it will answer many of the questions you probably have as a newbie.

Cheers and good winds,
