On the new houses, we can get Silver Line or Atriums for about $200 a pop ish. Double hung, vinyle, hurricane rated. They are OK for the money.

Were doing a higher end build now, and the owner picked Anderson which are about $400-$500 each, and IMHO suck. None of them close right, total junk. Atriums would have been better. They also had big snots of chaulk in the corners so they wouldn't fully close until that was dug out! None of the frames were straight, and they use an annoying hurricane bracket system. Took the framer twice as along to install them. I'm surprised because my dad installed this same window about 5 years ago in our house and they are great. Something must have happend.
Marvin or Harvey are the way to go for nice windows.
