Thoughts on this volt/amp meter

[Rocket61]

I'm looking for a well built volt/amp meter with a quick response rate to install in my dash. This is the nicest looking one I've found,

DC Programmable Meter Controller 0 200V 0 500A Volt Amp Power AH Auto Shut Down | eBay

What do you guys think? I like the 4 digit display on each line and the 5x per second sample rate.

Thanks for linking this, I've actually been looking for something like this to monitor my AGM battery and be able to have an alarm when it gets too low!
