MI Windows - The company generates good overall reviews for the V4000 (and higher) series, however, their V2000 and V3000 windows and doors are decidedly not up to the task. The company started out in Florida and now operates three manufacturing plants in Arizona, Texas, and Pennsylvania.
Milgard Windows - an excellent option for homeowners interested in vinyl, fiberglass, and aluminum windows and patio sliders. When coupled with professional installation from a trusted local dealer, Milgard is a very safe entry level to upper mid range option.
