Any experience with any of these? We are looking at the windows that qualify for the tax credit, but realize most of them do and it comes down to finding a good installer & taking a look at the air/water infiltration numbers.
Quotes for 5 standard windows have been anywhere between $940/window (Sears) to $453/window (Excalibur).
This is a great site and I look forward to hearing from anyone.

Thanks!
