I use Lockton Affinity from PPA. There's some shortcomings but they've immediately paid out every claim I've ever made (including for drones) so I have very few complaints.

I work with a local independent insurance agency. My liability, business owners, errors and omissions, auto, and equipment policies are all through Liberty Mutual - there also an umbrella policy and an Inland Marine policy through a different company. It costs absolutely nothing to have a local insurance agent review your business and advise you.
