We use Cablevision Flow/Fibertel with 100Mb Internet and hundreds of cable channels we never watch. For this we're paying around AR$2800 which seems to increase every month, just like everything else.
There are other players in the market including Telecentro and Claro fibre optic.
Telecentro 100Mb is $1876 with IP phone and hundreds of HD cable channels over IP.
Claro 100Mb fibre optic is $950 with one IP phone line.
Considering we only watch Netflix and sometimes Argentine news channels and football/rugby when there's a major championship, I don't think it's going to be a difficult decision, as we're burning money at this rate.
