In the American market which is vast compared to the irish one once the manufacturers moved to China and could make a ready to run wagon for about 5 dollars more, the Kits have virtually died a death.

I bought a CP Rail C630m with Tsunami sound and then fitted a BC Rail pair with Loksound select. The ESU Loksound wins hands down on both sound and motor control. I will post avideo of the two sometime I have a minute.
