Hi everyone! You have been such a great source of information! I want to get a general poll of what everyone things about OKNA 800? I'm planning on ordering these windows. Also, how can I tell if a window installer is "good"? I found a company based on two recommendations on this forum. Plus the google reviews and yelp reviews are great.

Finally, SDL is $112 more and I have 25 windows. I'm thinking of putting the SDL on just the windows on the first floor (where there is high traffic). I would do grids between the glass on the second floor. I don't know how this would look from the outside of the home? What do you think?
