Nice looking volt meter -

2" volt meter w/white face (http://www.harborfreight.com/merchandising-promotions/merchandising/gigantic-tent-sale-august-2011/2-inch-led-lit-voltmeter-gauge-98479.html)

That looks like the exact meter I have ready to install on my scoot. :smiley_th

Is there such a thing as a voltmeter/ammeter combo? Isn't this a good idea to install one - or am I way off?
