I would say to go with the buggy that has the most parts at your LHS. They are all great buggies and honestly you can't go wrong with any of them. Each one has their own strengths and weaknesses, but that really doesn't matter much. The worst thing (especially for a racer) is having to wait 2 weeks for a part in the mail or having to pack up and leave the track early due to a broken part! All of those cars (including the Xray) are winners.
