HI
I have Argos platinum I have always found that quite good. They have paid out when I needed it too.What you need to be careful of is if it has a maximum that it will pay in 1 year/ a maximum it will pay for an illness. The best ones are the policies that offer whole of life so if they end up with a problem they will be covered for that for the whole of there life. I am not sure about what Argos offer so it worth a poke about. Be careful though the cheapest is not always the best way to go!
