See, the problem with a response like this is... I just did a search 'car mount' and this is the thread I got. I know it's a vicious circle, but it never hurts to give a little advice as well as suggest a search.
I like the Proclip, but I think it's overpriced for what it does. Others are gonna say "you get what you pay for", but I'm planning on going with the $25 Arkon universal mount with 15" flexible neck that mounts to the passenger seat floor bolt. If it lasts 6 months, then yes, I got what I paid for and will be happy with that.
BTW, try searching "mount" instead of "car mount". The more broad your search phrase, the more results you'll get.
