Hey, thanks for the response, 750SS. The Classic is a premium unit and I'd really like to find out if the tach stepper motor is stable. $500 is serious money, but I love the look and integration in the Avon fairing shown in the photo above. I have some other questions regarding its use with an ARD magneto, but I suppose if I'm really serious about the purchase, I could contact the manufacturer for specific installation information. However, please give us your first-hand impressions of any installation and usability issues when you have the unit working. Thanks again! RR
