Which Groupset?

Not being a dentist, or millionaire mobile operating system/application botherer I've never been able to afford anything more modern than 10 speed Campag, so have no frame of reference other than the cycling press.

Wherein, you have to admit, the level of technical development significantly favours the fishing equipment makers over the "LOOK AT THE SHINY" boys from Italy.

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?
