I'm looking for a decent FM transmitter for my iPod video . I have an iSkin on it to keep it from getting scratched, so I need one that plugs into the bottom with a cord instead of a cradle. I had a cradle type one in my other car and all it did was scratch my iPod and if I hit a big enough bump it would come loose.

Which one would you suggest?
