You might want to go with a different Android device. I'd suggest the Moto X, it isn't over-sized, it's cheap, and it's a great phone (I have it, and its never given me any issues). Not to mention you can also customize its design (You can even get a real wooden back plate).
Also, I think on contract its only $0.01, you can go here to check it out and design your own:

An added bonus is they're assembled in Fort Worth,Texas so they say "Designed & Assembled in the USA" on the back.
