If those were my only options in my opinion it would be the 400 series. I am not a huge Andersen fan but their casements are not terrible. I would look into Integrity by Marvin they may not be much more expensive and would dam sure be a better window.

Find another dealer as I don't think that can be true.

The numbers should be close if not better for the Integrity.

So integrity should be in the same price range and is the best choice of everything out there in this price?
What about weathershield?

In my opinion Weathershield is junk

I would take Eagle first. Their new design is much improved from the previous window. Colors options are much greater then on the 400s, and you get extruded aluminum vs vinyl wood clad. Integrity wood ultrex should be the same price or close to the 400s. I recieved 3 different Integrity quotes on my home package, and they were within a few hundred of the 400s (400s were lower). However I will most likely go with either the Eagles or Kolbe due to color options and glass packages.
