I'm in Seattle and have 1gbps/1gbps for $80 (or 100/100mbps for $60) a month. I'm not sure why you are encapsulating all of Seattle in your post. Some of us in Seattle actually do have a decent selection for internet, although not a majority. All of my friends have decent connections, of at least 25mbps or more. I do feel for you, though, as it seems you are in one of those neglected areas of the city that has been shackled by the government arguments, and rights to run needed infrastructure being denied for cash under the table reasons.
I sure hope the situation gets better for you, but for some of us in the Seattle area, especially the people that don't watch ESPN, this is a practical option.
