The breeder pays for all genetic testing, which run hundreds to thousands of dollars.

IMO, it's worth the money. Hypothyroidism is genetically linked, as is hip dysplasia, elbow dysplasia, and a very large number of other disorders. If you don't think that it's worth the money, then don't do it. But I wouldn't purchase a dog that did not have any genetic testing done. IMO, that's worse than getting a shelter mutt; at least my crapshoot would be cheap.
