Wow they are pretty high. But any cable connection is going to be better then the 56k. I always tell friends that ask me if it is worth it that it depends on how much they use the internet. If you only use it for maybe a few hours a week to get mail and look up the weather then I tell them that it may not be worth the extra $10 - $20 a month. However, my Dad was having problems connecting to his ISP all of the time and I talked into getting cable, now he is using the internet more because it is faster and is always connected. You won't tie up the phone line.
It is too bad that you do not have more options in Broad Band but it is better then nothing, and 56k.
