Ya, I think so. If I was to buy the Dx6i on it's own, the 4 servos, HH gyro and a charger for a T-rex kit it would cost about the same as the B400 kit I think. And if I buy the B400 then I can hold off on the T-rex purchase until later in the summer or maybe even next year and I can use the 1 radio for all 3 helis. And from what I have heard the CPP has a great performance increase under DSM control.
