How do I best choose the least expensive surge protector for my 4 year old Apple laptop?

Lightning or a power surge won't care what you paid for it. A bigger question is how much would it cost you to lose the laptop from a power surge. You get what you pay for. Get one with a replacement warranty like apc.

I would recommend the smallest wattage / joule rated one designed for a laptop - avoid dollar stores, and definitely stick with brand name, particularly with warranty.

Personally for my laptop I never use a supressor, as modern power supply bricks are a lot more tolerant.
