I second the Hunter 9700 roadforce balancer, it is a great machine. However, if you browse through the dealer locator section on the Hunter website, the majority are the large car dealerships. You would expect the specialized wheel and tire shops to have these machines in the first place, but they all seems to be running crappy little balancers.
This pisses me off. I just bought a set of tires a couple of weeks ago, and the car was shaking violently at 110+. I came back to the shop to rebalance the tires twice, but the vibrations only gotten worse, although their machine showed a good balance. Took it to a shop that had a Hunter this morning, and they found one of the tires to be defective.
Such a waste of time and money. This is not the first time I have a tire problem resolved with a Hunter machine. Guess I'll be more careful choosing a tire shop now ;(. Hope they would at least honor the warranty...
