There is 1 thing about any "SEO-Solution" that is often forgotten:

Obviously links from SE's are very important to you, otherwise you would not even consider purchasing a script to assist with it. You should however always keep in mind that once you make the choice to go this way (no matter which solution) you have committed yourself to a mariage "for good and bad times, until death do us part". If you for any reason are not satisfied (anymore), you need to change product because it will not work anymore with a new vBulletin version, or any other reason, you will loose all your links that you have spend so much time on, unless you find a new product that will produce the exact same links to your content.
