you said you dont need anything expensive, but wiper blades are probably one of the few things that you would be a fool to go cheap on.
get the Bosch Icon blades, they're about $20/per side, but they will last about 5 or 6 TIMES as long as a traditional blade. this is the second car ive had em on, and this car has had em for about 5 or 6 months and they still work like new. i had the cheapo Trico blades before these, and they maybe lasted all of a month before they were streaking and were in danger of gouging my windshield.
im not one to spend more money on something than need be, but these blades will pay for themselves in about 3 months.
