I've used Montway Auto Transport (broker) on a number of occasions.

Found them through u-ship and then checked their prices directly on their site and always seemed cheaper.

Both times it was from southern california to NY state. Was under $1000 on each occasion. No issues and in both cases I had updates and communications directly with the driver as to the delivery schedule, etc..

Will use again if I need to.
