Hagerty for me as well.
If you are not familiar with Hagerty, it's not like typical insurance most folks are used to. Hagerty does full coverage policies for agreed value. How much it costs depends on what you're insuring and what the agreed value is along with the usual things like where you live, etc.
I spend $175 per year for two machines insured for an agreed $10k each located in TX.
The price includes all of the state required minimums for insurance, too, including liability coverage required to obtain registration.
I'd highly recommend checking them out.
