Agree with you on the nice windows.
Here is a thread I started awhile ago with a few alternatives regarding the windows, although maybe not with the quality reputation of Airstream.
http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/27374086.cfmWe checked out a Bigfoot. It was very nice. However, with that visit we decided we really want something with a slide to open up the interior.
The owners of the Bigfoot also pointed out to us that the Airstream storage is not as good because of the curved body behind the cabinets inside.
Good luck!
