I like the Krestmark windows. The look good at a good price. They built here in Dallas so it does not take long to get custom sizes. They are sold by many discount / surplus stores but I typical buy from Surplus Warehouse since they seem to have the best price. Tony in the Mesquite location is great.
Prices are better than the big box stores especially when it comes to custom sizes. They also have a good stock of standard sizes and the off the shelf prices are alright. 3ftx4ft vinyl double pane is about $120 less 5% for landlords.
