Really? Comcast also has similar caps and customer support is horrible but I pay around US$70/mo for 50Mbit/s downstream compared to something like Kabel Deutschland which seems to offer 100Mbit/s downstream for US$22-44/mo (lower price is promotional for first year). Also, while I bought my own modem and router to avoid Comcast's additional rental fee, the German company includes it in the cost. I don't doubt that they also suck in terms of customer service and will take your word for that since I don't have experience with them. Still, unless there is something I'm missing, it would seem that you can get double what I can get for 2/3 or less cost. (*disclaimer: I only looked into some popular cable internet providers and looked at their site to get a quick overview. If I'm missing some detail that customers would know about, I would not be surprised.)
