if you have flown a 3m kite and enjoyed it, what make and model kite was it?
it may be a good place to start.
what is your weight? if your a skinny runt, 60kg, start at about 2m, if your a heavy weight 95kg+, 4m, in between 3m.
buggy wise (no punn intended) Bobm in this forum has a decent second hand PL buggy for around $300 plus post from canberra. (if its still available)
also, would you prefer to buy a new kite or go for second hand.
second hand can be a lot cheaper, about half the cost.
i would recomend to start with a fixed bridle foil kite, and then when your skills improve, you will try more types, and go from there.
the demo system here in XK is the best, join up, and try a few. only problem is the system can take quite a while for you to get a demo kite. maybe Goz can advise you as to what may be currently available without too much delay.
keep asking questions, as you see you will get a few variations in the responces, take it all onboard, but you have to decide for yourself which way to go.
one tip i would give is do not be in a hurry to get a harness and connect yourself to it. take it slow and as your confidence grows, get tougher with the kite, chuck it about the wind window and enjoy the thrills.
try and locate other kiters as near to you as you can, try their kites, if they are XK members you wont have a problem getting a fly or three.
welcome to the forum and kiting.
