You aren't going to get many people to respond to cable modem questions, because first of all, they are all about the same. You probably will not get better performance from a Toshiba vs. Motorola vs. Linksys. Secondly, most people probably rent from their ISP, only a select few have actually purchased their own.
I am personally looking at the Linksys one myself. You can get it for less than $100 at dell.com. Good deal I think....
