You can of course just use your multimeter for this, These are great if you want to build the project in an enclosure, making it completely stand-alone.

The "Ultra High Accuracy" ampere and voltmeters from eBay seller elite.element seem to be a great fit for this project:

Basically, I found the milliammeter very suitable and found a matching voltmeter.

I have no affiliation with the seller, but I have ordered these.
