Some are missing the point.

I am paying for a FORUM. I'm not paying for anything else but a nice, clean forum. If all the bells and whistles were necessary, then I'd definately choose vBulletin. However, I fail to see a real reason to pay for vBulletin anymore when I can get something like SMF. A forum script that works just as well as vBulletin and has a lot of the nice features vB has through mods for free.
