Well, in windows 8.1 they added the start button back, but all it does for the moment is take you back to the metro start screen (the screen with all the tiles on it). Microsoft does plan to add a fully functional start button soon though.
I would recommend getting windows 8.1. It's not that much different from windows 7, and it actually has some pretty good performance boosts (ex: windows 8.1 boots faster than 7). Also windows 7 is no longer supported by microsoft. This means no more service packs.
I agree with Donny, and would recommend windows 8.1. However, I believe that Microsoft support for windows 7 won't expire until early 2015, see the link below (near the bottom of the article)
