I love the idea of not having to replace my shifting cables/ adjusting them every few months however, the price is a huge deal for me. I ride my bike to work every day and while i did shell out 200$ for a new 105 crankset, I don't want to have to pay too much more than that for lights/shifting. Maybe a di2 version of the lower market shimano group sets would make that more feasible as a cyclist who doesn't mind occasional maintenance
