It sounds like you are looking used, which is the right thing to do.
For more forgiving boats : In the used kayak section for sale of the site, there is a Karma Large, Karma Medium, and a Liquid Logic Remix for sale. All about your size.
Your size is similar to mine, and your a dead ringer for the Medium / Large playboat divide.
If you get a playboat, you will be able to boss around a medium. Learn to roll and go find a play park!!!
