I'm looking for a through the wall dog door. I currently have the Plexidor brand, and have not been happy with it for what I spent for it. While it's as quiet as promised, I've had to replace the springs in the door almost yearly, and the two swinging doors often don't quite meet when closed allowing cold drafts.

I'm currently considering the Endura Flap Pet Door, possibly the double flap model. Has anyone used one of these?

I'm looking for something that can be installed in the wall, will be weathertight, and in a size for Tollers and Labs. Suggestions are most welcome.
