The best budget disk are Deore if you ask me. Like Ali said, you get a but of pad wobble but it didn't bother me too much. I took mine straight off my hybrid and put it on my stock with the Avid 180 rotor that was on already and it was amazing from the off.
I don't understand how adjusting your lever affected the pad wobble. Fair enough if it did like but I thought pad wobble was caused by the pads having room to move in the caliper.
