We used these guys about 7 years ago:
They used to be out of Coquitlam and moved to Surrey. We have had no issues with the windows. Most were simple sliders, but had the master bedroom and living room done with casement and they came out really well. We've had no issues with workmanship. If I could fault them on anything it was that it took forever for them to actually get them installed. Their manufacturing process was a lot faster than their installers could keep up with.
From a price perspective, they were good as well. A friend of mine who is a builder gave a thumbs-up on their price and quality when he saw the work completed.
No idea how they are now, but they were good back then. Maybe check a few current references.
