WTB: Doggy Door for sliding glass door

[animuL]

I've seen these around but I don't know the best place to get one. If anyone has one for sale or some info on where I should look it would be appreciated!

I have one for the screen door on the sliding glass door. Here's a link to when I got it, sorry I deleted the pics already, but it has a link to where I got it.
