Over in some other forums, there seemed to be some general consensus that the best protection is to install a whole house surge protector (that I believe is also TSS? rated) at the panel, and then use the kind of surge protection mentioned by the other gentlement at the device. What to use at the device seems subject to a lot of discussion, but (at least to me) the "defense in depth" makes sense.

You also should be careful to address other paths such as telephone, satellite and cable tv connections.
