Environmental Potentials whole house surge protection, can I get your opinions?

Thanks everyone, it looks like this is more complicated than I thought.
Eric- your Home Depot link list many different units, did you have one in particular that you would recommend?
Jea48, thanks for the links, though they seem more geared to an industrial setting. 
It looks like the layered approach is the way to go. 
So, what do any of you recommend for the mains box?

Thank jea, but that model specifically states that it doesn't protect from lightning strikes-which less common in my area but definitely a concern.
And, I definitely will be using a licensed electrician to install.

I saw this Siemens unit, and wonder if this might be a good choice:

That Ufer ground looks very interesting. Thanks for bringing it up. I am always amazed by what information can be gotten on the internet.
Whart, don't worry about hijacking my thread. I enjoy learning new things.

So, it seems the ground may be a place I should be inspecting more closely. As my house is almost 100 years old, is there any way to test a ground? Or, is there any way to add a newer/more effective ground?
Thanks Bob

Sorry, I was away for a while and missed the fireworks.
In any case, my electric was gone over in 2000, the grounding, which was never tested, looks like a submerged rod just outside the house with a clamp holding a thick wire (copper?). 
Any ideas finding someone on Long Island to do this testing?
