I've had the same Anco ones for about 1 1/2 yrs. I've learned to be careful how I scrape in the winter. If it'* snowing when I'm done driving I leave the wiper blades in an up position, this way it'* easier to scoop out the snow and scrape off the ice.
But if you really want to get fancy check out this place
SSEi95 got a set from there, I don' know if he hooked them up yet.
