I also happen to be a big fan of Snapnames. However, I will not buy the 3 move limit snaps. I buy the full snaps instead as owner reneweals and other grab services make the limited option less desirable...example, I had a FULL snap on MuscleCarWorld.com and my NameWinner bid of $8.75 caught the name.
Using both NameWinner and SnapNames is a must and I have even started using DropWizard as well. UltSearch is kicking everyones ass! The more services trying to catch a name for you the better!!!
