West Window Corporation-Nuweld Replacement Windows?

We live in North Carolina and a neighborhood realtor, who has rental properties, suggested we look at a local installer of Windows. The installer uses West Window Corporation, Nuweld II windows. The website looks fine when I review the windows and the quote came in at 2768 installed, but I can't find any feedback from a homeowner who has used them. We have also had another company quote Seaway windows, who many of my neighbors use. They are roughly 4500 installed. We are only having a few windows replaced.

Does anyone have feedback on West Window Corporation, they also sell these brands-Allweld III, Dualvue II, Nuweld II, Westweld II,
The Westwood, The West Elite.

This is our first window replacement. Don't want to get stuck paying for something overpriced since often we do our own work.

Have you tried looking for some of the more well recommended brands that are discussed on this board?

I have not heard of the window personally.
