I've been very happy with my Omlet door, you can see my review and others' reviews of different automatic coop doors here:

For me, it was worth spending a bit of extra $ to have a door I knew would be reliable and have customer service. I'm handy and could have made a door, but I am busy with work and other house projects plus I didn't want to have to worry about the door while traveling.
