Can someone recommend a dock for my iPhone?

I can’t seem to find one that has the features I want, and my list really isn’t that long!

1) It must plug into the wall, not connect to a computer through a USB.
2) It must be able to hold my iPhone with the case on. It’s just one of those plastic cases that fits right over the phone, but many of the docks seem to be the exact size of the phone.
3) I want it to be small!
