Don't know about the price, but I'm quite happy with the 4g variant.
Downloading official kitkat for it right now, 4g speed is nice to have, and moving apps to sdcard keeps this thing open for tons of apps + additional room for more. So I see no real advantage to the internal only one here.
Probably better to base it on your storage needs + some additional for growing room / additional app space. If you don't put/keep whole video files, tons of music, recovery backups, big games, or other things that take up lots of space on your phone then internal only should be fine. There's nothing wrong with it.
