I second the PIAA's, mine have been on now for over 3 years, and they still work great.

Can't say that for any other set of blades I've used in 28+ years of driving

 

After shipping the Valeo's are $27.26 to the bay area from Tirerack.com. Looks like the driver's side is backordered though. Anyhow, the Michelin's from Walmart are $15 and they work great. They are a few bucks more but you don't have to wait for the UPS guy to show up. I have the driver's side (they didn't carry the passenger's side at the time) and it is amazing. These are the new "Aero" style wipers that are on newer Mercedes and are $75 for a set. Regardless, I recommend both of them. Don't go for the traditional wiper blades anymore. These are better and the wipe is much cleaner and does not streak like traditional blades do.
