What's a good portable 42in travel crate?

[s14roller]

Does anyone have a recommendation to what they use as a good portable travel crate? My dog has a 48in at home, but it's a bit too big to fold and store into a sedan.

I'm thinking of getting a more portable (easily to fold/collapse and transport from home to home) crate for her.

Anyone have any good recommendations that I can get at the local Petco/Petsmart?

Thanks!
