Any alternative for dual listbox control?

Is there any alternatives or other approaches - from UI perspective - for dual listbox element? In general I'm used to apply the Dual Listbox (as described in the example). The Dual Listbox should serve the user to manage, edit and set two lists of variables. This is a major activity that the users needs to complete. It's a new product that we develop and the users are from the financial arena (C Level). I have a good experience with Dual Listbox for this particular task, but thought maybe there are additional alternatives that works better and or to broaden my set of features to use and embed in future products.
