Best(cheapest) Bike Insurance, Especially WA State?

[3Chief]

I'm paying $660 a year from Geico for bike insurance on the f6b with pretty high coverage limits. Anyone found cheaper? I'm pissed at the lizard for jacking my car rates after years of loyalty, I'm looking to dump them on every count, car, home, bike. S'far USAA is nearly $200 cheaper on car insurance. Anyone have any advice, thanks up front.

I have two bikes insured with State Farm for about $440 each a year, I have another on a really old Farmers Insurance plan that's roughly $300 a year.
