Snort. I had a Renewal by Andersen guy in before I knew any better, and he quoted me almost $2000/window. I pretty much laughed him out of the house.

I ended up getting Sunrise Restorations put in, and liked them well enough that, after moving from Boston to Colorado, I've just ordered another set for my new house. The Boston-area Restorations dealer was recommended by another poster here; low-pressure, helpful, and no BS.
