Everybody says if you ride a Di2 (or any electronic group) bike, you'll never go back. I figured I wouldn't even test ride one because I didn't want to spend the $$. Then I wound up test riding a Di2 bike because it was the only one they had in my size and I didn't even like Di2 at first. I came to love it but it took a few rides. Apparently I'm the only one. You took to it right off the bat, everybody seems to.
As to the $5K, have you tried Photoshop and a color printer?
