We use which has offices in Modi'in and Jerusalem. They are native English speakers and are insurance brokers so they will get you the best deal from one of several insurance companies. We had a major claim (always the real test of an insurance company and your insurance agent), and they went to bat for us with the insurance company which was playing games with us.
We have been very pleased with them. We also have our homeowners insurance with them. They explain all your options but don't give you a hard sell.
Their number is 1-700-70-6660. The particular agent we use is Danny Newman. A real mensch.
