I'm def a fan of waterless detailing products, and $100 sounds really cheap.
Last time I inquired about getting some one to detail my car they wanted to charge me $300 just to polish it (stating he had imported polished from the US that were v.expensive), I didnt take up his offer to polish but instead paid $60 to get the interiour cleaned (feeling kinda ripped of now :P).
Will post up some pics of the waterless detailing kit that I use later on.
Car looks sweet
