Someone else mentioned Bosch... They're like $17 a blade if I remember right, but I've had very good luck with them - very long lasting, great for winter. I think they have a line of them now with some really pricey ones, but I just get the basic ones...or I should say one since I only use one wiper now. If your car is going to sit outside for a long time in the winter (in someplace like New Hampshire, maybe
?) Maybe just take em off and leave them in the car. I can't imagine a situation where it would be difficult to remove snow or ice from those little hoops on the wiper arms.
...I do not work for or endorse Bosch.
