4DSC said:Mothers clay kit is another favourite, and sometimes easier to get. It also comes with a full bottle of the Showtime QD that's mentioned in that recent "favourite QD" thread.
The only (generally) unliked clay seems to be Meguiar's.
What's wrong with Meguiar's clay? It is the only readily available clay from where I come from. Any other brand, I'd have to order and get it shipped.
