Residential windows

[forgop]

Looks like I may be getting all of the windows replaced in my 21 year old house here shortly and is something I've never really researched. I currently have BiltBest windows and it seems as though they have gone out of business.

I worked for a builder at one time 15+ years ago who said Pella was the best so they're definitely in the picture. I know Andersen is also a respected name and wondered if I'm missing anyone else.

I thought given the fact I'll be in the market for 20+ windows, I will get pricing from the manufacturer direct and then bid it to window installers to quote windows + labor. Thanks!
