Recently we had a member who saved $13,000 buying windows for his log home using a tip from our log home building class.  Yes, he bought these windows for pennies on the dollar.  Click on the thumbnail to the right to see the actual windows he purchased.

The windows he bought were used , and he said that they "looked practically brand new."  They were made by Anderson Windows, a name brand manufacturer, and are part of their 400 Series. 

The Anderson 400 series is completely clad, providing protection for the wood frame even if the windows are left open when it's raining.   The exterior cladding is vacuumed formed, so there are no miters / seams (common failure points).  In fact, the Anderson 400 series of windows are noted for having very good casements.  They also use high performance Low E-2 insulated glass, making them very energy efficient.

If you go through 'traditional' retail avenues it is easy to spend $10,000 to $20,000 on just windows.  We've had members spend as little as $100 getting all the windows they needed for their log home using tips that we cover at our log home building class.
