Before you do anything go get an outlet tester and make sure that the house is wired correctly.
Consumer-grade surge protectors don't last forever.
Most of the less expensive ones use MOVs. Those components really have to be considered to be sacrificial in nature. Once an MOV stops a surge it has to be considered unreliable. Most of the time they fail 'shorted' and wil continue to pass electricity. MOVs also just plain get old and wear out irregardless of whether or not they've stopped a surge.
Surge protectors are cheap enough. Replace them often.
Instead of a simple surge protector I would go with a UPS in the range of an APC 1400 or something like that. Sure, the thing costs about $150, but you'll get far better power protection and conditioning.
A mid-good range surge protector will cost you in the area of $100 anyway. The extra $50 is good insurance.
Save the surge protectors for the laser printer. Plug your ink jets and PC and monitor into a decent UPS.
If you can find a salvage company that sells 'dead' UPS units, try there. Most often a 'dead' UPS just needs its batteries changed. Sealed lead-acid batteries have a life of about 30 months. Batteries Plus will swap out the cells in an APC 1400 for about $50 and recycle the old batteries too.
I've got 5 UPS in my house. 4 NetUPS 1400s and one NetUPS 500.
One on the PC, monitor, small HP b&w inkjet. Small things like the USB hub are in there too.
One on the cable modem, router, and switch in the utility room.
One on the phone system and raid box in the utility room.
One on the home entertainment center (TV, cable/DVR, and stereo).
The NetUPS 500 runs the Canon i960 and i9900 printers since they are in a closet in the office.
There is also an 'industrial-quality' surge protector wired directly into my breaker panel. The thing is made by GE, cost about $150, takes up two breaker positions, and installs just like a circuit breaker (meaning that it's DIY if you have the skills to work in a breaker panel).
The GE whole-house unit comes with $50k of electrical damage insurance.
Don't laugh at a whole-house surge protector. Take a walk around and add up all of the 'electronics' you have plugged in. Don't forget the dishwasher, oven, microwave, washer & dryer, clock radios, etc, etc, etc, anything that has a display or LEDs or a timer.
