Hmmmm, I assume that you're probably looking for magnet cars at the moment so personally I would recommend somthing like scalextric mustang, gt40 or lola.
They're all nice and quick, giving good handling and don't have too many bits and pieces that are gonna fall of when you (inevitably) crash.
With regard to controllers, I've never used the SCX ones so can't comment. I would certainly recommend parma controllers. I upgraded from the standard scaley sport "on/off switch" and the difference they make is astounding. Gives you a much greater feel of control. Some will recommend 25ohm for home racing, personally I think 45ohm is more suitable (particularly for beginners) but it really depends which one 'feels' better to you.
