Autometer has a new one too, it's like a copy of Holley's Pro Dash, they have a direct fit for A Bodies now, it's about $1300 though, which isn't much more than I have into their 6 gauge setup for A Bodies.
It's got 4 different layouts you can choose from. I just wish you could add a couple more gauges to it as well, or a second page with more info, like the Holley setup (for twice the price).
