Its all in finding someone to do a good job with it. Very scary to have a wheel with imperfections like that. I also recommend finding a shop with a high end wheel balancer. One that applies actual force to the tire while its spinning.
I heard HPP Racing out of Lewisville Tx can have then done for around $200 per wheel. I also like the look of the pp wheels... Hmmmmm........ big and littles would look pretty cool.
