Last year I had Top-Up-TV, mostly so I could watch Eurosport, but when both they and ITV covered it, ITV's commentary was so much better.
This year I don't have TUTV, and they don't broadcast Eurosport at the time you need for TdF anyway (at least not with the bog standard deal).
Since I'm not at home during most of the race midweek anyway, ITV4 highlights are fine for me, and free.
