Harbor Freight often gives a digital one away when you buy literally ANYTHING, I've got 2-3 of them.
I have both analog and digital meters, each one has advantages on certain things. You can't see a swing with digital and analog will not split hairs on volts like you sometimes need with digital. Analog are great for checking mag impulse proximity sensors as well, a digital hasn't a prayer doing that. Like battery volts, often the difference in your problem can be one volt and hard to see that on a needle device. The difference in charging or not is MUCH easier to pick out on digital.
