we've got ours through AA, previously with IAG (State) through HSBC bank and to be honest I'd go without insurance rather than deal with a bank again.
AA seem quite good, has someone write off the back end of her car a couple of years back and no problem getting the stated value - they even added the bit extra they got from the "at-fault" drivers insurance (who for some reason paid more than the stated value)
Anyway's I also have my camera gear listed as part of the home contents although I had to get Progear or Ak Camera do a valuation it's quite worth the $25...
some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:
