We went through a couple doggy doors in your Yakima house. I bought them out of a dog supply catalog and ordered the most expensive version offered, figuring it would be the best. I was wrong! It fell apart after about two months of moderate use, and the magnets on the flap never did seal adquately. Oh, and it was made in China.
When we built our new house, we wanted something with true, lasting quality. I searched on the internet and found this website: http://www.petdoors.com/. This California company (Patio Pacific) sells nothing but pet doors, so they're familiar with the problems inherent with the cheap old catalog and pet store versions. From Patio Pacific's selection, we picked the "Endura Flap" door, made in the U.S. and made to last. The quality was evident as soon as we opened the boxes.
The Endura Flap is holding up very well. It's mounted lower than some of the others we've had, making at more negotiable even for old, feeble guys like Atlas.
