Anyone who told you that is being untruthful. All Spiders come from an original founding animal. All Spiders have the capacity to wobble at some point in their lives and in some way, either minor or major. That right there is the reason you should want to purchase from a quality breeder. I agree with Ed and Walter. Don't be afraid to get an animal shipped to you and don't be afraid to pay a little more for quality. It's not all about price...
