I am in the process of getting my parts and tools list together for a Team Losi Type R. Its always good to find out what parts break alot and have spares on hand. I like it because its different from the rest. All the cars out there have batteries on one side, electronics on the other.
The Type R has the batteries right down the center, and parts are not as expensive as say a Xray or Corally. One thing you should keep in mind when shopping for a car is parts support. What will your local hobby shop support so you don't have to keep buying parts on the internet as well as does anyone at your track run the car you want so you can get setup help.
I think most people buy two cars one for foam one for rubber because they don't want to have to make drastic setup changes and of course because the have the funds to do it.
Another car that I have kept my eye on is Team Magic. Their suppose to be coming out with a E4JS model which is tailored to hobbyist on a budget. Might want to look into that one but again if your local shop is not stocking parts you will be on the internet looking.
