I am also switching from TSI DSL 6m to Start 45/10 cable and I hope my transition goes smoothly. My DSL is done on the 14th and my tentative install dates are the 10th, 11th and 12th.
rocca is spending enough time here, so, he is able to cover everything.
sometimes, i really feel bad for him, as we sometimes go crazy with questions, etc, and he is not getting much rest because of that, but, thats the life he chooses ! :P
Their support (e-mail \ phone) is the fastest support i ever seen since i am using internet in my life.
so far, you can't go wrong with this isp.
I never experienced any bullshit from them. If there is a problem, they don't lie about it, they don't try to hide it.
The way i see it, once the problem occurs, they jump right on it, which makes them (in my opinion) best ISP out there, so far (at least ones that i tried, and i tried many that are mentioned here. (Velcom - used to work for them, TSI, EBOX, etc).
