I did get a quote from Clarion today for $350+ yearly w/$250 deductible and waiting to here back from two others.
In the 40 years of playing for money, I've not had coverage and only had one issue and that was last year with a Demeter amp taking a dive off of a cabinet. I had to send it to James to get it fixed.
I have a lot more expensive gear now and I'm having concerns about it not being covered.
That seems like a lot, but I don't know how much stuff you have.
