The Buzz is good fun but is really a beginners kite and being a two-line kite can be a bit limiting in the long-run.
A four-line kite like the Flexifoil Sting might be a better bet. They range from 1.2m to 3.3m, I have a 2.4m (along with quite a few other kites) and it's great in lots of wind conditions.
I take it pretty much everywhere, and I always throw it in my suitcase when I'm going on holiday, it's a great kite to let people have a go with if they haven't flown before, and I even use it as my buggy kite when the wind is strong. They handle really brilliantly and are just great fun to fly.
Worth the extra cash over the Buzz, and for me Flexifoil are worth the extra cash over lots of the cheaper makes. Brilliant quality and great back-up service from Flexifoil.
