Stop in for a cup of coffee

As I stood looking at meters the other day at Harbor Freight I wondered which one I should get.
I've never owned one, but feel the more I do things on the cars I need one.
At least my mechanic neighbor wouldn't have to walk back to his house to get his.
Any recommendations....what it should have on it??
My favorite analog for kicking around in the tool box is a mid 80s Radio shack multi-meter.
For digital, so far I've been pretty happy Innova 3340
