I love my Kaku Wahoo 12.5, it is super stable and affordable.  The kayak has an open deck, pre drilled for a micro power pole, rudder ready, setup with several gear tracks.  The kayak tracks very well so no need for a rudder unless you really want one.  Easy to paddle and fairly fast for a super stable kayak.  The company has exceptional customer service, most times you can speak with Kevin the owner directly.
