I think that all the high end cars like the FK'05, RDX, 415ms etc are good cars. I drive an FK'05 and really like it, there are some RDX's at my local club and they are also very nice. Go for something that your local hobby shop supports, it makes life a lot easier when you need parts.
As for shaft vs belt, i find that belt is easier to drive.
