Okna 400 v. Okna 500
Just got a quote on Okna 400 and Okna 500. I know the differences between the two windows, but am not sure whether the price differential justifies going with the 500. Can anyone help?
Quote was about $350 per window for the 400 and about $460 per window for the 500, so around a $1500 difference total (we're replacing about 13 windows). We expect to move in about three years, so would not recoup the money in saved energy costs. (We don't have central air and our baseboard radiators only yield about a $150 gas bill per month, at worst, during the winter-time.) The 500 would come with triple-pane glass, incidentally.
My gut is telling me to go with the 400 under the circumstances, but I usually don't like to pick an entry-level model. What do you think?
