OK, I know this has been posted quite a few times but it's all a bit confusing for me

I think I need to think about insurance properly having upgraded by kit.
I guess there are two trains of thought - increase your household insurance to cover personal possessions away from the home, or buy insurance from a specialist camera insurer.
My current home insurance is with Halifax which unfortunately doesn't have my address in their online system, so I can't check online quotes. I'll give them a call later to find out. But generally, what am I looking for? Is it personal possessions insurance with accidental damage and replacement on a like for like basis?
I know through searches on avforums that some people use a company called
Photoguard. From other forums I've found mention
E&L,
Glover and Howe and
Aaduki. I've heard from friends that E&L and Photoguard are pretty tricky to claim from. Anybody got any experiences with the four companies I mentioned?
Also, the specialist companies offer public indemnity. Not that I plan to make a living from my work, but people say I should get this even if I was shooting a wedding as a favour. At least, with a specialist company I could go for a regular package and upgrade with public indemnity if I ever needed it. Does that sound sensible or is it over the top for my needs?
And lastly, how does all the above work for bringing my kit on holiday? Going to Morocco next week for a photo holiday so alot of my kit will come with me.
