I'm in the middle of building a custom home, and have been doing research for days on window choices.

The builder has selected a Simonton ProFinish Contractor Gliding window, which seems to be a pretty good product overall, but I there are some things I am not real happy with.

For instance, I do not like the choice of Grid patterns. I know this seems superficial compared to the quality of the window, energy efficiency, etc.. but it does contribute to the overall aesthetic of the home. Plus, we have to look out these windows, and the grids are just annoying to us.

We would like to stay with a Sliding/Gliding window, but we would like the appearance of a single hung via a grid/grille.

We are also have pets, and we don't want them to be able to push the window open to far, so we want some kind of latching mechanism that prevents the window from being opened too far. I believe these are called Vent Latches. I know Andersen has something called a Window Opening Control Device, and maybe this could be added after market, so maybe it's not a huge problem.. but something built-in would be nice.

We really like the Andersen 100's Tall Fractional grille pattern, and there are good reviews of the Andersen 100's (and my builder says he's happy with them), but I don't really like the latch hardware on the Andersen's, as it's an auto-locking latch. I prefer the peace of mind of feeling the window locking with a manual cam latch. I love the Marvin slider hardware, but those are just insanely priced.

I've been looking at various other windows.. but the problem is that I have no basis to compare the costs, because you can't find the costs of these windows online.

So, I'm looking for a window that has similar pricing to the Simonton ProFinish Contractor or Andersen 100, but offers the features i'm looking for. Things that are important:

* LowE Glass - North Central climate - very cold and very hot
* Durable Screens - again, we have pets.. and don't want them to bend or warp the screens
* Low air infiltration
* Good Warranty - At least 20 years
* Solid company - can back up that warranty
* Cam hardware
* Don't need fancy finishes.. standard white vinyl is fine, both in and out.
* Laminated security glass if possible for lower windows
* Grid Pattern - Tall Fractional (2 or 3 upper lites) or upper fractional (small blocks along the top) or even an upper cross (top half). Custom grid would be ideal.

If it's not possible to get this in the same price range, then i'd like to at least know what kind of price difference i'm looking at. Obviously, I understand that pricing varies and that my builder may add on, but he claims he doesn't.

So, to any of you out there that are in the know.. any suggestions?
