I am preparing to have new windows installed. We have narrowed down a contractor, but now we are choosing between brands. We are looking at Anlin Del Mar, Anlin Mar Vista, and Milgard Tuscany. Obviously Anlin Del Mar is the higher quality as it has a much higher price tag, but is it that much better ? Not sure it's worth the extra money over the Anlin Mar Vista or the Milgard Tuscany. Any insight would be appreciated.
