Agree with TJ and Tony, except that I honestly don’t think that from the point of view of a newbie, the driving styles will be all that different. At least, its not like the difference between a TaG and a shifter or a TaG and a 100cc Yamaha. I think at this point you are concerned about subtleties that won’t mean much at your level of experience and the more important question is whether you can find something in your price range that is supported at the track you will be racing at. Try and find something that already is set up to be fast at that track so you don’t spend your first year scratching your head and wondering what to do to make it fast. And that is supported by a kart shop you trust, because these are racing machines and they WILL break and you apparently won’t be able to fix it yourself.
