Many like the Acratech, Arca-Swiss, Markins and RRS heads but unfortunately they're mostly expensive. Induro is a Benro brand and while I use a Benro tripod and like it I'm not so hot on their ballheads.
I would look at the Photo Clam range, I've used one and they are well made and good value for money. There are members here who use and like Photo Clam ballheads who will hopefully chime in - like the Markins they are copies of the Arca-Swiss Z1. I use a Z1 and can tell you that it absolutely and positively doesn't shift as you lock it down!
