What do you consider decent? Gigabit only? You can get at least 60-100 Mbps in most towns, as long as you aren't out of town. Probably gigabit if you're willing to pay a lot. Spectrum is the main option in the big towns. Looks like you can get gigabit from them in the big towns for $110/month for the first 12 months. Not sure what it would go to after that.

100-200 mb/s is decent for me. I can multiplex multiple cable modems so not a problem. It would be great to get something at the edge of town that has a lot of land, but I might have to settle for DSL.
WA has some municipal fiber networks. In my county, you can get hooked up if you foot the bill to extend the network to your property and find a retail provider to service your account. There's an online map that shows where the fiber currently is, you'll save a bunch of money on fiber construction if you build near where it already is.
Depending on the area, you can't even get internet outside of full cities. I own a house that's a few miles outside of a small town in Oregon. When I moved up here from the bay area recently, I had to rent a second house in the nearest city 30 miles south because there is absolutely no terrestrial internet service even within the city limits of my ~700 person town.
