You will get there eventually Stas. I've been lusting after a Cobra for about 20 years now.
I've got the Tech Edge 2AO wide band O2. It's got an LED display you can put on the dash while tuneing but it's not very pretty. They've got a new guage similar to the ones in your link that I might have to look at.
Here's a link to the Tech Edge site:
