Hello! We have all Marvin ultimate windows in our house in a dark wood. Aluminum on the outside and wood on the inside. We have two bedroom windows in the back of our house where we need to replace the windows. Is there any alternative to Marvin ultimate that might be comparable but slightly more cost efficient? We are getting a quote of 10 K for these two windows and because they are in the back of the house on an area where you don’t see the front and also where the sun doesn’t shine hot. I am hoping we can find something a little more cost efficient. A different Marvin line or a different company? we live in Los Angeles if that matters! Thx
