Finally got my hands on a 3.813, after buying about 5 on eBay. The winner was a buy it now with a concealed display, and it came at a decent price. The rush of seeing 3----8----1-----3 show up was like winning the lottery. I will have to take a drive around later, I've only been messing around with it on a power supply.
On a side note, I couldn't leave all my radar stuff alone, so I brought it to college & will still be doing concealed displays.
