Many years ago, I picked up a Carrera 1:43 set on a whim. I dug it out so my daughter and I could have some fun. I was thinking of picking up another set so we could branch out and make our own custom course.

The questions:

Is 1:43 an established scale? Are there other brands making 1:43? Are they interoperable with the Carrera gear?

I know we are not talking huge money here, but why spend $ to expand if the product is an oddball scale that has no support.

Any input appreciated.
