While it will be burdensome to maintain his cost of moving, the added bonus of being able to start with the key member of this 'spot' heavy culture for free more than makes up for the price.
Having Gandalf from the get go, you can now start Radagast, more Ents, or even some fun companions like Erland, Dale Counselor and carve through the site path with Gandalf holding the ring!
