How much will the iPhone 5s phone bill be?

I just really want one and if it's reasonable, maybe I can get one.

Added (1). I would get the 32gb because I'd like to have room for my music and apps so the 16gb wouldn't be enough. But the 64gb would be too much room and it's just so expensive. I'd consider anything under $70 to be reasonable. Are there any deals out there?

I think this dear smartphone comes in to three 16, 32, and 64 gb models! Also its last gb must be around $1000 and the prices are different from place to place because of the law of the place, tex, etc! You may check the up to date price in one of the trustable phonesites?!

So just what exactly do you consider "reasonable"? It is a $650 smartphone.
