One that comes with lessons would be a really good place to start.
Your instructor will then be able to reccomend equipment or at least give you some feedback. Probably something around the 10m to 12m kite size and 134 -137 board size. I am your weight and ride a 128 ( some say that it is too small )but a bit bigger board is easier to learn on and you can get put in slightly lighter winds.
Lessons first
