Already bought the Campy group I wanted for my new ride in the spring. Athena, alloy, non-electronic. I'll consider a new EPS group in a few years if I have a reason to buy another new group. I have spent time on lots of groups, from different makers, though my SRAM experience is the smallest. I mainly decided on Campagnolo because I liked the feel of the hoods the most, and once I had one group, I like it and figured there was no reason to change.

Oh, and a word about Shimano's $2billion revenue, they make a whole lot more than just bike parts. They're also a fairly major player in fishing equipment and I'm sure other things as well.
