17" LCDs that pivot 90 degrees?

I know there are plenty of "which lcd should I buy" threads, but which are the best 17" lcds that also pivot 90 degrees?

I know samsung has addons you can purchase (we have them on the 172N's @ work) that allow for 360 degree pivots. I dont know of any that COME with 90 degree pivots though.
