UPS for power regulation?

[Billy SG McCarthy]

My parents have a fairly old house, such that there is
only 1 outlet in the room where they have 2 computers
(and some lights, etc).  The computers are never both
running at the same time, but it still makes me a bit
uneasy, 2 full power strips, 1 plugged into the other.
 

I was thinking they should get a UPS and plug
everything into that.  Does this make sense?  If it
does, how powerful a UPS should they get?  If not, any
suggestions aside from getting an electrician to put
in more plugs?

thanks.
