If it helps Paul, I started using Imaging Insurance in June 2015 (I had just bought a big hunk of Canon L glass, and the thought of dropping it, or getting robbed, house fire, car crash etc was on the mind!). I was at around the same value of kit as you.
I did plenty of research and looked at a lot of web reviews, I like to make the right choices. I never buy an insurance product just on price, so I'm not into meerkats and comparisons! I want a solid company with a history of fairness. As part of my work (which is not photography), I have met many insurance company executives, and the insurance game is generally about taking a premium and never having to pay out! So you have to choose the right company.
Imaging Insurance gave a good price and communicated the best of all I contacted for a quote. I haven't had to claim, so I can't give you any experience on that claims. However many reviews indicated they were a good company when things went wrong. They also didn't have any silly clauses, I did hear some won't allow you to claim if you go near water or cliffs etc
I found many of the companies I approached weren't much good at giving quotes, advice and just simple communication! and I did choose some leading names to give qoutes.
Home insurance is ok to a point, but watch out for limits and clauses, if you have some expensive kit, I would avoid it.
I noted that there were quite a few websites with buying advice, and many of the forums had members with experiences, I used that info to make my choice.
Good luck with it, I made my choice, but like someone said, you don't know if it was a good one till things go wrong!
