I recommend this: http://www.thelightningdock.com/products/iphone-5-dock

I have two of them, one for my desk and work and the other next to my bed. They're great because you can adjust how far the lighting adapter sticks out for different cases and there's nothing else to obstruct device. I found both of mine on eBay for less than retail. There's not typically a lot on there but if you're patient they seem to pop up occasionally.
