They are about $15 at lowe's, home depot, etc. The only issue is you have to be sure your wiring to your house is grounded (if you have old knob and tube wiring, they wont work) -
Or, they have GFCI surge bars, I saw some at walmart a little while back, for like $20 - so the wall outlet is cheaper, but since you are renting, the surge bar option may be better......
If you can go with the ones hard wired into the wall, would be better off.
I've heard many stories of the surge protector bars with "GFCI" built in, failing to do their job.
