Depends on what style your headed toward....
But i suggest a 3 strut surf kite like
Switch element 4.... 5 7 or 9m .
Great kite good drift good depower easy relaunch and around 7 to $800 brand new.
I have 5 and the build quality is as good as my ozone edge v8.
You would go from beginner to Intermediate and beyond with this type of kite.
