Yeah, in the US at least, this is the way to go, you can like well over 10k coverage for $100 or even less a year, no deductible, equipment covered under any circumstance and you don't risk tying it to car or home insurance and messing that up if stuff happens to your equipment.
Unless you are a pro photographer earning you living from it, then you need something else.
My State Farm personal articles policy covers about $9K of equipment. All-risk (in other words, everything is covered), zero deductible. $84 per year, or roughly 1%. If I make a big equipment purchase then I just send an updated spreadsheet with serial numbers to my agent, they adjust the amount of coverage, and send me a bill for the difference.
