I have the 50/5 plan from Time Warner as well, and it's definitely best option around. But 5Mb upstream is still pretty chintzy.
Go up to Dallas and you can get 50/25, 75/35, 150/65, and now they're rolling out 300/65. It gets expensive on the extreme end of that, but I would sure love even 50/25. Major, major difference in upstream bandwidth.
No, it's not. TWC's TV/Phone/50Mbps Internet plan costs me $170 a month. (I think I have HBO in there too.)
Now incidentally, a firmware update bricked my cable box and I haven't had the desire to talk to anyone at Time Warner about it, but $170 is a fine price for 50Mbps Internet. (I don't use the phone either. Again, not wanting to talk to anyone in a call center, this is the best I could do.)
Their DNS does lie about NXDOMAIN responses, however. If you try to resolve a nonexistent domain name, it returns NOERROR and an A record pointing to their servers. I run my own DNS server fed from the root servers, so I don't really care, but I thought I'd mention it. The technician that did the install was also not happy that I didn't have a Windows or Mac computer for him to insert a shady-looking CD in. "What kind of router do you have." "It's an OpenBSD box." "..."
(I had Speakeasy before and kind of miss them. 24 hour phone support, and they were always extremely knowledgeable. Someone I talked to once also used OpenBSD at home.)
