I have an Ameristep Dog House and like it. Just finished my second season with it and it is holding up pretty well. I leave it out for several months unless it is going to be really windy. The poles do poke through the sleeve area some so that is annoying. It folds down to a pretty compact size and comes with a pouch with shoulder straps so you can pack it in if needed.
Since I leave mine up a lot, I am looking at getting a bigger one that is made of heavier material.
