Look into Anlin in Socal, they make a very nice window.

Installer depends where you live.

I would strongly consider fiberglass windows such as those from Marvin and Milgard. If you're replacing single- or double-hung windows, consider casement (and awning) windows as these are the most energy efficient. Take care to understand glass options, particularly for west-facing windows where noon-to-sundown sunlight can easily overheat a room. Chosen carefully, energy-efficient windows can help reduce heating and air conditioning costs where electricity prices are high.

P.S. Our 10-unit condo installed Enerlux fiberglass windows and patio doors which have performed well. You might call the company and ask whether it has a Southern California installer/partner. We had to find our own installer in DC.

Reasonable prices and SoCal don't usually occupy the same sentence.
