Marvin is probably the "Cadillac" of wood windows. I assume you are talking wood, not vinyl. (?)
Try checking into Loewen, Hurd, WeatherShield, Vetter, Windsor, or Semco. If you want clad wood windows, Andersen or Pella "wood" fit the bill.
You might be better off visiting a local millwork shop and see what all they can get instead of shopping online.
