We are looking at replacing our 'original to the home,' General Alum windows, and are getting quotes. We are are in Austin. Randy at Ultra Windows unfortunately doesn't service our area....yet

Below is a list of the windows currently in the house. We intend to stay in the home for 20+ years, so we want to buy something that will not only last, but provide the best performance. The home faces SW, so we get a lot of afternoon sun in the front of the house.
Four 36x84 - see below for separate transom windows
Two small transom windows above two of the four windows listed above: 35x23/20/11
One side light: 14x83 (needs to be tempered because close to front door)
Two 36x12
Two 48x72 (one tempered because close to door)
Three 49x96 (half moon above each)
Two 24x72 (one tempered because close to door)
One 72x108 (half moon above - currently two single hung side by side with one half moon window above)
One 24x35 (in toilet closet - frosted)
One 48x60 (above tub - tempered and frosted)
Two 36x84
One side light: 14x59
Two 35x59
Two sliding 59x47
Two 35x59 - see below for separate transom windows
Two small transom windows above the two listed above: 35x23/20/11
So far, we have received the following quotes. Company listed first followed by the window. Nothing fancy with vinyl colors - all white:
1) Zen Windows: Soft Lite Classic Plus: $35k
2) Texas Window Store: Vista Mark Endura: $28k
3) Texas Window Store: Provia Aspect: $32k
4) Texas Window Store: NT Windows Presidential: $32k
5) Zen Windows: Imperial elite: $48k
6) Energywise: NT Windows Presidential: $30k (8k to do split frame)
7) Energy one: NT Solar Pro: 34k (13k to do split frame)
Is pricing ok or are we getting raked across the coals? Does one stand out from the rest? I'm leaning the NT Pres route, unless one of the others stands out completely. Haven't tried negotiating any prices yet.
