I signed up the VVD communications last night and the guy came to install 11am today. That's really quick. When I test with the ethernet I get 20Mbps down and 10Mbps up. That's super fast!
When I test with Wi-Fi (Airport Express) however, it just gives me 6Mbps down and 6Mbps up. Maybe something's a little screwed up with .11g connection between Airport express and Windows XP. I reconfigured AirPort to do .11g only and set the WAN ethernet limit to 100Mbps Full Duplex, but I still don't get luck here.
Anyway it's definitely better than Comcast and will switch soon (and cancel Comcast for just a month). I signed up a monthly ($40) this time for an evaluation but apparently they raise the yearly subscription rate from $300 to $350 next month, so I need to decide soon.
Now I should've known this service 2 weeks earlier. I paid $36 the first month and $25 one-time installation for Comcast, and $40 the first month and will pay $300/yearly (or $350 in the worst case) for VVD. I'm spending $150 more ...
