I personally like the ProClipUSA mounts, but they're not cheap. Excellent quality stuff, though. I think Brodit is the european equivalent.
You can also 3d print a mount for pretty cheap.
And of course Amazon is full of mounts you can buy.
I tried the clip Karlis has, but it wouldn't fit my 9-3 vents. It fits my wife's Pilot vents perfect though; it's a great mount if you can use it.
