I have owned eTap for a year now. The only other local I have seen with it is my LBS owner who built himself a Moots with eTap, but he sold it shortly after because of geometry issues. There are a few DI2 bikes floating around, but probably over 90% mechanical here probably because there is not a huge road bike market here. I love eTap! I recently test rode a new Tarmac with mechanical Dura Ace. Shifting felt like pulling the arm on a slot machine compared to eTap. I have ridden Ultegra DI2 as well. Electronic just feels so much faster shifting to me.
