Has anyone crate trained using a divider in an Impact crate?

My boyfriend and I are getting a German shepherd puppy soon.

I like the Impact crates because they collapse and have a handle for easier traveling.

What was your experience crate training with an Impact crate?

Was it easy to clean?

Easy for travel?

Did you crate your own divider? The Impact divider is $200, which is insane.
