Regarding the Zephyr. Great low-wind to mid-range-wind kite. If you're just starting out, don't get one unless you plan to leave it in your bag for a year and pull it out when you're ready for it. Any beginner will probably hate it. Unless you are very familiar with how to adjust a dual line sport kite for a specific wind type and speed, you will have it adjusted wrong more than half the time. The kite is designed with inherent instability so it can be tricked well. This will drive you nuts until you gain enough experience. I had one and am telling it the way it is. Eventually I loved it -- but until then . . . .
And I'm not even talking about tricking it, just getting it to fly with some control. It has a very small range of compatibility with existing conditions. You need to have it "dead on" or it will cause you grief. Bridle, stand-offs, weight position, and sail tension must all be well-coordinated. You will eventually learn to use all of these adjustments to your advantage if you stay with it. If you think kites may be a temporary passion you're just increasing your level of frustration in what should be pure joy. You don't have to fly as well as a pro to have fun.
