Depends what you are willing to pay, remembering that the value of your gear to the cost to replace it with new. Lots of specialist firms out there, my advice is check all their small print and what they cover and maximum amounts for things like gear Stolen from your car, but we're talking car insurance costs depending on your gear. The problem is, you only get to know how good or bad the firm is when you have to claim.
You could look at covering your gear with your house insurance, depends what they'll cover as individual items. Problem with my house insurance was maximum single item was £5000, got a few expensive lenses that cost more than that if I replace them with the new version
