How do I collide a Kinematic sprite ?

I'm working on a "Zelda: Link to the Past" style game and the hero drags a chain weapon behind him. The chain requires the hero have a rigidbody2d component to attach to.

Because I want non-physics type movement for the hero, I made him kinematic and use transform for movement.

According to the table here: http://docs.unity3d.com/Manual/CollidersOverview.html

..my only option is a Rigidbody Collider, however, this doesn't actually stop the hero (like a wall) and instead allows the hero to push it around. I tried to make it fixed but then the hero passed through it.

How screwed am I?
