cost of upvc windows

can any one give me a rough estimate on replacement windows and doors, for a normal 3 bed semi det.
1 front door
1 back door
1 french door
6 windows
I wont hold any one to prices, but dealing with window companys is just so frustrating, I just need an idea
thanks

where are you based? I got great deal on my new build from Martin Reid in waterford. great service and windows. black PVC. www.windowsdirect.ie.
