No, I wasn't aware there's anything real affordable like that, so I'd be very interested in this for my own house! I've seen a few true divided light double-pane windows, and in fact have one for my back door and side lights, but those seem to be more expensive than rebuilding the old. Most of what I see people putting in old houses is single-light double-hungs with oddly-reflective low-E glass and a false grid. They just don't look quite right on an old house, even from a distance. Ah... different situation, entirely! There's an outfit I've dealt with in New England that still makes traditional windows, on antique machinery. All thru-mortised sashes, glazed panes with cope-and-stick mullions, rope counterweights, you name it. Very nice stuff, and they were covered by Roy Underhill's show on PBS, maybe 10 years ago. I have their info somewhere... will try to dig it up!
