If people want straps with metal mesh embedded, or a Pacsafe, there's details on all the Pacsafe products here
. I notice that they're about to release a photography insert for their duffel bag, but it doesn't look as well designed overall as the Lowepro Stealth Reporter D650AW I use when I'm carrying all my kit including my laptop. Nevertheless, a bag with the mesh embedded would be useful - it's not often I could make use of a Pelican case if I had one, but a shoulder bag is useful to me.
Ciqala - your add-on cover with HSBC seems quite reasonable. My Glover and Howe amateur policy costs me around £220 per year, but I am covered for £8500 (20D, BG-E2, EF 16-35mm f/2.8L, EF 24-70mm f/2.8L, EF 70-200mm f/2.8L IS, Speedlite 580EX, tripod, head, laptop, portable printer, filters, hoods, bags, straps, memory cards, odds and ends). The cover is UK and up to 60 days worldwide for the photography kit (the laptop and computer bits are UK only).
It's amazing how the value mounts up. The cover is, in some ways, superior to an ordinary household policy, as it's based on new replacement and my understanding is that, unlike most insurance, betterment is possible. The aim is that stolen items are replaced with nearest equivalent - for example, if my 20D was stolen, I should be left in a position to buy a 30D now that the 20D is discontinued.
I'm also allowed to do things that I doubt household policies would allow, such as leave up to £6500 of kit in a locked car during the day, and it's covered (nevertheless, I have a Category 1 alarm/immobiliser, I lock the bag down to a tie-down loop welded into the car's floorpan using a Pacsafe, and lock the boot manually so that opening the central locking is insufficient to gain access).
I scan all my receipts and upload them onto my hosting account (outside the folders that the web server uses), so that I can get at copies if there's a fire at home and my filing cabinet is destroyed. I also keep details of all my kit in a spreadsheet, which makes keeping my insurance records up to date much easier. I note down the purchase price and date of everything in the spreadsheet, but also keep track of replacement value, which isn't necessarily the purchase price and is what I'm required to insure for.
