Had a good deal (I thought) on 17 windows for $4,200 installed, reliabilt 5600 dbl hung, low e/argon, grids, screens - much better looking fit and finish than the pella thermastar sold by Lowes.
BUT Survivor just went out of business

doh! Anyway I like the windows and for the price am very satisfied, but the warranty won't do me much good now for getting a matching replacement if I need one.
