Agree, that's why I referred you to W8JI.  His site has survived lightning 
strikes, but it takes some work and money.  You asked about an alternative to 
ICE or some other kind of lightning arrester device.  

An ICE or any other plug in device to your coax won't protect your gear from 
direct lighting strike if that is what you are looking for.  The power from one 
of those lightning strikes is awesome.  I've seen them set houses on fire and 
splitter large trees.  Your choice, disconnect everything or spend some money 
and work.
