automated workpapers

I was wondering what software is being used by internal audit departments to automate workpapers.  My credit union is looking at ViClarity for various modules including internal audit.  I have no frame of refernece to compare against other products (other than Pro-system workpaper manager) and would like some input.  Please let me know what program you use, if efficiencies have resulted, if report format is acceptable, a ballpark figure of initial & on-going cost, & if you would recommend the product.  You can respond on the forum or email me directly at [email protected]  with information.
