Welcome to very fun hobby !
If your looking for an rc i would look for one to first get used to and practice with thats fun instead of looking for a buggy that you can race right off the bat. Usually if your going to get a buggy for racing you do need to have good experience because with racing comes a lot of replacing. So if your looking forward to rc i suggest you get a buggy that will just be for fun for awhile, then later on when you more experienced get into the racing scene.
I personally have never owned a buggy so i do not know what direction to give insight on but i know the other very knowledgeable users will be able to guide you the right away.
