I am pretty sure we paid the same for the full lite and the 1/2 lite doors. Here's a closeup of the frame where the door transitions to glass. As you can see, there is no plastic raised frame surrounding the glass like you see on the doors at HD and Lowes. It looks more like the ones you get from the window manufacturers. Here's the only pic I could pull of a Thermatru door with a screen vented lite. I would make sure you saw this in person before ordering... What about installing a retractable screen instead of the vented lite? Also, if you were going to leave a window treatment on the door all the time, you could attach those sticky-backed magnets to the door and then use a magnetic curtain rod to hang it from. Maybe one of those ones that you can raise & lower?

Go with the grids that you want in the future (i.e. contoured) and the others will match better once you change out the rest of them. As mmarse said, it is unlikely you will notice any difference from about 10 feet away so I wouldn't worry about the exterior look for the time being.

This is actually interesting timing for this thread. I am in the process of having my house re-sided and new windows/doors put in. I ordered the grids between the glass on the front windows, but they got the order wrong and they came without. In order to keep the project moving, the GC installed the plain windows and ordered new ones wtih the grids. Last Thursday night, the windows were replaced. My neighbors - even those who are anti-grids - all have made a point to tell me how much more finished the house looks with the new windows. One person commented that the windows looked like black holes before the grid and now the windows look balanced with the siding. (See pfmastin's comment above) I've had strangers stop to do the same. From the inside, I really like the windows so much more. The view out the front is not gorgeous, but now when I look at my windows, I have that fuzzy new windows feeling I just didn't get with the plain windows. Granted, true wooden mullioned windows have a ton more character. They also are not a smart upgrade in my neighborhood and would likely have tripled to quadrupled my window budget. They are also hard to clean. I took pictures of the front of the house with the first version of the windows. Maybe just for fun, I'll take some new ones and post here so folks can see the difference if folks are interested.

If you are using white everywhere I would use the same sheen as all your trim- why carefully cut in if its all the same, the sheen won't matter when the door is shut.
