        Why not "kill two birds with one stone". Why not "bullet-Proof" your
network and PC systems with a Uninterrupted Power System?  (UPS, not the
parcel group!) It provides superior power protection from utility problems,
blackouts, brownouts, sags, EMI/RFI noise and surges.
         I learned this while in Bosnia with AT&T as we used an APC
"Professional Powercell" which is heavily lightning/surge protected on the
AC power side and also has a protected telephone line-in and line-out to
your modem/computer. 
        We carried a whole satellite terminal, computer stn, modem, T-1 and
even a work light and a solder gun, just for "human engineering" purposes.
The APC units we used there were programmable for 115/220VAC and 50/60Hz.
They were a back breaker to lift onto an equipment shelf or work table, but
they held the sags and blackouts and we would seldom lose a track of the
        They were so popular there, the local in-country post exchanges
ordered them for their computers/NCR cash registers at each camp and post.
(BTW: NCR is owned bt AT&T as is LUCENT).
        Advantage: It's protects power spikes, as power companies dump their
primarys which really spike the secondary to home delivery. Plus, whatever
model you purchase will depend on your computer load/station loads. 
        It's an AC to DC to AC converter with a replaceable gel cell which,
depending on usage, should last between 3 to 5-yrs. In life, as in business,
there are no guarantees. We have power disruptions here and loss of inputed
data, w/o storage,  can be frustrating.

        APC Toll free customer service support is excellent, IMHO. Hope this
soliciates your attention to detail.
