What do you all think of the digital air/fuel gauges at gadgetsellers.com?

It says in their description that they aren't as responsive as the autometer...is it a big issue? I'm trying to decide between the digital gauge or a modified autometer cobalt gauge?

I actually have one installed in my car. When you go WOT, it doesn't display the a/f voltage as quickly as the "blinky" meter, but the response time is so minimal (we're talking about fractions of a second). I don't think it's anything to be concerned about. I like like because the digital meter displays a solid number when you're WOT.
