The Hobby Town I goto has a great selection of TC3 parts but there service is pretty bad. However, it is the best place to go when buying a new RC. Right now I would just like to goto a track and try it out first before I decide if I want to try to compete or not. I've seen some on-road courses on videos that look like they were professionaly built with cement bumbs painted red and white as the barriers and resembles an acctual race track. Others I've seen seem to just be some plastic tubing with some wood. Hopfully we'll find a central track that everyone with an on-road can get to one day.
