Which Decoder Should I Pick?

Thanks for the info.

The locos I am considering first are an Athearn Genesis F3A and a Walthers Mainline F7A/F7B. Both state they have NEM21 sockets(?). The other locos are four Atlas Silver C420's. I am not sure what type of connections they have.

I guess I am going to see what 21 pin decoders there are.

In the instructions for the Walthers Mainline f7's it says that you can use an adapter to go from the 9 pin to 21 pin.
So far this is the adapter I have found. https://www.walthers.com/dcc-decoder-har...54cm-wires
