Looking for a better report writer than Acubench

We have been succesfully porting our legacy app to the Thin Client but now need to replicate a lot of our reports. AcyBench is horrible when it comes to report writing. Is there an alternative for this? A large amount of our reports are written in troff but I am looking to have more reports that are written through the app and would be made availabel to the thin client user instead of having it done through the server.
