Accessories Adjustable air vent holder?

I'm looking for one of those mounts that snap on to air vents in the car. I drive a newer civic, and if you've ever been in one, the windshield goes like 5 feet into the dash :p It makes it borderline impossible to mount anything on it unless it's right in your face.

I keep finding clip holders that will hold a naked phone, but I have a slim case on it and I'm not sure if they will fit those. Does anyone know of one that has adjustable "arms" on it to accommodate cases?
