I do not want the most expensive - nor the cheapest. Home Depot is currently offering a $340 installed vinyl window (with low e / argon / grills) from American Craftsman (division of Anderson).
I am comparing that to the Pella Thermastar - sold by Lowes. The Pella is about $425 per window.
The salesman at Lowes also offered a Reliabilt window and offered some reviews - same specs as Pella - but - 1 inch glass - for about $400 per window installed.
Is there a difference in quality / longevity of these 100% vinyl windows ?
Thanks SO MUCH for your advice !!!
