Which Groupset?

Reading the cycling press makes difficult to choose. It depends also by the journalist who tested the groupset, and by how much the three big companies are ready to pay for a good review. I personally prefer opinions based on forum users.

"Not being a dentist" didn't you have an Ultegra Di2 before? Is it not more expensive then a 10 speed Campag?

I've got Dura Ace Di2 on one bike, Ultegra Di2 on another, I still can't afford Campag.
