I'm hoping to find out more about this, too... I am heading out on the road through Central America to shoot a web tv show and am not leaving the country until my $10k of gear has some sort of insurance on it...

Short Term Insurance is a killer. If you write 3 policies a year, you've basically paid for year round insurance.

Here are my two thoughts:

For short term in Los Angeles, there is a company called Filmmaker's Resource on Sunset Blvd and all the rental houses and people know them because they end up producing your project with you as a producer, as a result, you fall under their insurance policy. It's the cheapest way around your own policy.

For long term, if you primarily do post production, you can often get a better rate. You could contact Bill Blake at media plus 4 insurance. I have my year round policy with them. You can tell him Mark Allen of Allucinari suggested you call. One thing you need to know about them. They seem to be the best rate, but their insurance certificates are SLOW - like up to 24 hours unless you call and push them. Most places have like a 15 minute turn around. It's pretty standard that you need them same day - so that is something you'll need to take into consideration when evaluating the price, but I hunted around a lot.

Danny at Digital Film Studios suggested someone the other day and I don't remember off hand - but hopefully this gives you some good options.
