Most companies will come in around the $250 - $280 mark but that will be door to door. Northline are another company ive used in the past a lot.. never had a problem but you do have to pretend its a business you are shipping from and to.
EGo will be the cheapest if willing to do depot to depot.

All shipping of pinballs has an element of risk and no transport company will have a perfect record, all i can say is that ive never had a problem with any of the two companies mentioned
