DCC Dynamis

[tigerthelion]

I am very interested in upgrading my bachmann dcc control to a dynamis control... which one exactly do I buy? I am a little confused... there are two and one costs more than the other... I think I understand but a little explanation would be great! Thanks!

The one that costs more you want the system, not just the handhold controller. Part #36505 is the one you want do not get #36507
