vBulletin.
 

Hello all.
I personally think vBulletin is awesome!
I just think, it's overpriced.
I would get it, but I'm not paying that much.

Your not the first person...
I think its really worth it, depending on what your looking for
If your just looking for play around site or just for fun i would recommend something like phpbb. But for anything serious , Its worth 160 of a OWNED license

I disagree, I think for what you get, it's more than worth the money. It all depends on what you want to use the software for and whether your buying it with the intentions on starting up on a commercial level or whether it's a hobby.

With that said, there are plenty of free alternatives none of which come close to what vBulletin provides.
