If you have the room do this...I went to Lowe's and bought a kitchen cabinet without a top. Its the one that the sink is suppose to go in. It has two doors that open in the middle and one on each side plus two drawers. I got a piece of plywood and covered it with batting and an old sheet and set it on top of that cabinet piece. That takes care of your wobbly problem. And there's not much engineering to it. =)
