ISOBAR is a good suppressor for sure. One of the best!
I use APC Surge Arrests (around $45 USD at Best Buy or like store) and they have done well for all my computer equipment. In fact, last year I lost my router and a hub that were not plugged in one of those APCs and everything else survived the surge from that electrical storm.
I have since plugged my new router and DSL modem into a second APC unit! Like them alot.
But you wouldn't go wrong with ISOBar either for sure!
