That is exactly what my LBS in CA said. Di2 is reliable and they are recommending steering clear of sram for now. They are not happy about having to deal with the etap problems. That info was too late for me as I was an early adopter. And, ironically, my very first etap groupset is flawless so far..
I've worked a 2 different shops that feel the same way. Neither shop stocks SRAM equipped road bikes, and special orders pay full retail.
