I bought mine on ebay for 250.00.
The CI gauges are pretty basic and use dip switches that were easy to set. The only thing that bothers me is the oil pressure gauge is off by 10 lbs (low). They say to send it back to be recalibrated, haven't yet and probably won't.
I only have them cause they less expensive (on ebay) then others when I was looking for some. That was several years ago.
You can see pic of gauge here.
