The answer I am hoping for is very very difficult! We are buying a house right at the top of our budget (and over asking price) which has these. The sellers have just asked for half the installation price to leave these in place. Are they really going to be worth them taking if we can't pay? They want 2 thousand! Our coffers are bare but will be sad at the naked windows. (We could probably grub together 2 hundred but if they are worth taking to a new property I expect this will not be attractive.....)
