Thanks for the quick recommendations. If only I had half the windows to replace, they would be well under my budget. Oh well, wife would not agree to replacing all 23+ windows at that price + installations. Thanks.
You shoud be able to get 23 decent windows installed for less than $650 including installation.
Or you could go out and buy 23 rolls of plastic wrap. Tell her this is going to be the cheapest way to fix the windows.
