Hi Robin,

The earth/voltage trips should be fast enough to protect your
computers, at least the power supply side of the equation. If you're
happy with the power supply protection, you might be able to find a
phone line protector that is cheaper than the combined power/phone
extension lead. As Nik suggested, try asking a qualified electrician
for advice.

The advantage to using something like the multiway extension lead in
you situation is that you get phone line protection too, and that (at
least with my Belkin one) the manufacture offers a guarantee if your
equipment gets damaged while using one properly (<tongue-in-cheek>What
have the Romans ever done for us</tongue-in-cheek>).

And one last thing, my Belkin extension lead has 6 sockets, so they
are available in smaller and larger sizes.
