Yes it would be better to get one with vac also. This will let you know how well your engine is running and also if you have a vacuum leak, it will be easier to see and diagnose because you can see the gauge.

Exactly get a 30-0-30 gauge

Also, though not really practicable with a small dash gauge (they're not reactive enough):
