Hey Pancho !! welcome
First : get in contact with your local kite school and take lessons , your teacher will be the best suited to advice you which kite size board etc is better for you .
You will save lots of headaches , time and at the end money
Then whatever questions you may have you are always welcome to ask around but donÃƒâ€šÃ‚Â´t forget to mention your weight / local spot / level . why ?
Weight : kite / board size you may need depends mostly on your weight
Local Spot: wind & water conditions are also important
Level: Some kites / boards are better suited for beginners
Just a tip : material starting year 2007 and up can be considered very good ( since most of the kites are so called 2nd generation SLE / BOW kites ) .
