its been a while but I thought this was something that just started happening? was the motor just built? if so its on the builder and its free. motors dont just get out of balance, I really dont know who is doing your work but there is no way to truely determine an out of balance situation without tearing the motor apart and doing a rebalance. I know you may not want to drive an hour but really you should bring the car to me and it will get fixed correctly. If by some crazy mystical way your motor did somehow get out of balance its usually 250$ for the balance itself but that means the motor is coming apart and the rings,bearing, gaskets will be replaced so you will be around 1500$ for a rebuild on the motor and 500$ for the R&R of the motor. weather you choose me or someone else I strongly reccomend you get a real shop/builder to check your car out.
