I'm thinking the same as tedw that a matched pair of Yeeco meters from Amazon is the way to go. They look nice and are easy to read for a reasonable cost. jdennis says the Yeeco voltmeter is accurate. Just need to confirm that the Yeeco AC ammeter really is AC and accurate.
A word of caution for anyone who thinks it's easier to go with the proven solution of the American Hobby Distributors RRampMeter. If you're considering the less costly Version II with enclosure, the specs for the Version III say it will work below 7V due to having battery back-up. To me that implies the Version II will not work below 7V.
