Disclaimer: I am related to Eylean board development
One more tool is Eylean Board - it is virtual board which offer both scrum and kanban tools. You can customize it anyway you like through a simple GUI. I have to say the board looks pretty nice and is very fluent with drag and drop everywhere. And of course it has cycle and lead time reports. One thing is that Eylean must be installed on client machine it is not a web app.
