How ironic and good timing,
I am also looking for replacement and was liking Sunrise UltraU and Softlite Barrington as a step down. But Sunrise was pricey for a couple that doesn't open the windows and too old to need 20 year windows.
Just called a local home remodeler with good reviews and someone I talked to a couple yaers ago on cabinet hardware--very nice
Will see how they compare in price to the Polaris Ultra
