Put a 6 volt headlight bulb in series with your 6 volt power source (use both filaments). It will limit the current in the event of a short, but should provide enough power to run the motor. Now you c ...

Yup - either of those suppliers should work.

I'd look for a part that's maybe 5 ohms cold (inrush current would be less than 3 amps) and can handle 8 amps (100 watt bulb) or 10 amps (130 watt bulb) ...
