I have an extra XD-16. I used it for a wideband,but it can be used as pretty much any gauge if you have the right hardware. It looks like they are about $200 new. So, $100 plus shipping takes it. I have the LC-1 that goes with it, it works perfectly but seems to show a sensor code. I dunno why, I suppose for $75 more dollars I will send it too.
