I just randomly saw this and liked what I saw and am willing to tell people who ask what I do if they want to see if something can be done. But really, EXTENSIONS = RISK. Write your own for full control, or look to free ones (this one), and ONLY after you've exhausted all other possibilities should you look for paid. This one looks good - and its free - should be first on your list of priorities. But nobody will be able to prevent FGU or other extensions busting you - its the RISK with them.
