Since today there`s another Hack/Addon for vBulletin-SEO available.

http://www.vbranking.com/

The Price is about 69,- € for Standard and 99,- € for Premium-Version. (incl. 1 Year Support guaranty)

Not bad. But I don`t think, that it can really match with vBSEO 2.0 Final.

PS: If I were you, I wouldn`t offer a Lite-Version. Maybe there are too many Admins, who decide not to buy a professionel version.
The "Premium vBSEO" should cost minimum 99,- €.
For many people quality, and prices makes an
impressive product indeed, and vBSEO will definetly the best Mod_Rewrite for vBulletin you can purchase for money.
