I really need a tach, but don't want to add a tach only gauge to my handlebars. Anyone have experience or comments on the digital speedo/tach combo now offered by Zippers? http://www.zippersperformance.com/catalogue/showproduct.asp?cat=588&prod=2098 I've read a few positive comments about Dakota Digital's unit. I was originally thinking of the HD speedo/tach, but these digitals have several additional functions for basically the same money. And, to be honest I like the different look of the digital stuff.
